Cisco WAN :: 2911 Multicast Traffic Stops Passing Through Multilink Interface

May 8, 2012

I have configured multicast (ip pim dense-mode) on two 2911 routers that are connected by a Multilink (3Mbps) Wan connection.The configuration work fine for awhile and sometimes all day but at some point one of the Multilink interfaces stop passing multicast traffic.I perform a sh multilink 1 on the interfaces and one interfaces show the multicast packets incrementing and the other does not, it just stops.The only fix for this is to hard reboot both routers and the multicast traffic begins to flow once again.

Cisco WAN :: 2911 Not Passing LAN Traffic To Public Interface

Sep 23, 2011

We have a 2911 Router running 15.0(1)M4. G 0/0 is our LAN interface, and it has three subinterfacesG0/0.1 is our data LAN, and the gateway for our Windows machines.  This is the interface this question concerns.G0/0.23 is a separate LAN for various equipmentG0/0.192 is another LAN for equipmentG 0/1 is connected to the internet, and has a public address.S 0/0/0 is a T1 PPP, connected to our core data centerS 0/1/0 is a backup T1 PPP, again, connected to our core data center.There are three static routes entered:ip route 100 This is the first PPPip route 200 This is the secondary PPPip route 255 It currently has a cost of 255 while i figure this one out. represents the cable company gateway, which I can ping properly.  I've also used "gigabitethernet 0/1" in place of the next hop ip with the same results. The public interface is properly connected, and can ping it's next hop (the cable company gateway).  When I change the static route for gigabitethernet 0/1 to a cost of "0", the router can properly ping DNS names, such as through the public interface. 
However, devices on the data LAN cannot reach any public addresses except for the router's public interface, let alone DNS names (I am using as my test IP).  If I revert the cost back to 255, making the PPP the gateway of last resort, these devices can again connect. (they travel through the PPP to our Data center's internet) 
This confuses me.  If our server, on the same LAN as the router can ping the public interface (it's definitley not leaving the 2911, as latency is less than 1ms), and the router itself can ping outside addresses, what is preventing the router's public interface from passing traffic to the internet from any source other than itself?  I have attached our running config in the hopes that there is something obvious I'm missing (the public ip addresses have been changed so they are not exposed).  I simply want clients on our LAN to get to the internet via the public interface of the local router, and still connect to corporate resources using the PPP links.

Cisco Routers :: RV042 Stops Passing Traffic On WAN

Feb 12, 2012

We have a managed service provider voip network that requires us to use our own router for the data network. We wanted to use the RV042 for it's easy vpn setup. After installing it worked great for about 10 min. then the WAN port stopped passing traffic. 3 min. later it started working again. We tested the RV042 on a different network and it works fine. We tested an older Pix on the managed network and that works fine. But the RV042 will not work on the managed service provider voip network. The service provider says that on their end it shows our WAN port going up and down.

Cisco VPN :: 3005 / L2L Tunnel Gets Built And Passes Traffic Then Stops Passing?

Aug 4, 2011

I have created an L2L tunnel between my self and a 3rd party. I am using a Cisco ASA 5520 and the other end is using a Cisco 3005 VPN concentrator. The tunnel will get established and pass traffic both ways for a little while, it varies, sometimes 1 hour or last time we built it it was working for 17 hours, but at some point my ASA will stop transmitting but it will still be receiving packets. These errors start to show up when I look at the traffic going through my ASA interfaces:

713042       IKE Initiator unable to find policy: Intf Outside, Src: 192.168.xx.16, Dst: 10.1.xx.30
Then when I try to ping their hosts .30 and .27 I get:
713041          Group = 68.23.xx.xx, IP = 68.23.xx.xx, IKE Initiator: New Phase 2, Intf private, IKE Peer 68.23.xx.xx  local Proxy Address 192.168.xx.16, remote Proxy Address 10.1.xx.30,  Crypto map (Outside_map)
 713041          Group = 68.23.xx.xx, IP = 68.23.xx.xx, IKE Initiator: New Phase 2, Intf private, IKE Peer 68.23.xx.xx  local Proxy Address 192.168.xx.16, remote Proxy Address 10.1.xx.27,  Crypto map (Outside_map)
 713050          Group = 68.23.xx.xx, IP = 68.23.xx.xx, Connection terminated for peer 68.23.xx.xx.  Reason: Peer Terminate  Remote Proxy 10.1.xx.27, Local Proxy 192.168.xx.16
When I first configured this tunnel it was with 3DES and SHA for phase 1 & 2, but when the tunnel would come up  my phase 1 would negotiate to an MD5 hash, even though I specifically entered SHA, so me and the 3rd party decided to bring all the hashes for phase 1 & 2 down to MD5, and that was when it was up for the longest, but the problem still came back eventually. My ASA config posted below:
ASA Version 8.2(3) 
name 192.168.xx.16 Server description  Server

Cisco Firewall :: ASA 5505 (9.1.1) & Comcast Business Cable Stops Passing Traffic

Apr 18, 2013

I am trying to determine why Comcast Business Class modem configured with a static IP (IPV4) works with a laptop or Linksys Cable modem but not with a Cisco ASA 5505. After a few minutes, the 5505 stop passing web traffic. I am able to ping the default gateway even though I can not surf the web. Restarting the 5505 and the Comcast modem, web traffic flows for a short period of time, then stops. I can connect inside the firewall via ASDM 7.1.1 and via SSH. I can not connect via either from the outside.  Comcast tech support indicated their router is working and is configured in bridge mode. I swapped out the 5505's memory, and then with another 5505. Nothing seems to resolve the issue. I am trying to determine if the 5505 or the Comcast router is not configured correctly.
Here are the parameters: The 5505 was reset to default factory settings via the command: config factory-default. Configured the outside interface with static IP Address followed by the no shutdown command, then removed DHCP features from outside interface.  Added Comcast DNS servers, default route, ntp servers, configured DHCP features on the inside interface. Enabled HTTP/SSH (inside & outside interfaces) and ICMP echo-reply (outside only).
I believe the Comcast modem is not configured correctly. The show version and show startup output are below.

Cisco Security :: Catalyst 4510 / Switch Port In Dot1x Multi-auth Mode Stops Passing Traffic?

May 6, 2010

I am experiencing a problem on a Catalyst 4510 (cat4500-ipbasek9-mz.122-53.SG.bin) with 802.1x configured. Client PCs are connected via a mini desktop switch to a Cat 4510 switched port in multi-auth mode. The configuration of the port follows:
!interface GigabitEthernet2/34 switchport mode access ip arp inspection limit rate 30 authentication host-mode multi-auth authentication port-control auto authentication periodic authentication timer reauthenticate server dot1x pae authenticator dot1x timeout tx-period 5 dot1x max-reauth-req 6 spanning-tree portfast ip verify source vlan dhcp-snoopingend
It happens from time to time that the Cat 4510 port stops passing traffic. Reconnecting the mini switch recovers the communication. Client PCs connected to the mini switch seem to be authorized at the moment when the problem occures. The RADIUS Termination-Action attribute is set to RADIUS-Request. The problem is not present if "authentication periodic" is disabled.

Cisco WAN :: 2900 - Traffic Not Passing From One Interface To Another

Jan 15, 2013

I am facing a very big problem with site to site vpn on cisco 2900 ios.
I configured the vpn and when i ping  from router itself to destination ip with source as lan interface , VPN works, no problem.
but when i connect any computer directly to router's lan interface to initiate traffic , it doesnot work at all. and on computer's lan i see yeloow sign.
mtu is 1500, speed is auto (I tried changing also) , duplex is auto ( i tried changing also) , through firewall on pc should not affect but still i disabled it.
since their is no problem with vpn config as vpn comes up when i initiate ping from router itself but i dont know why it is not working from lan.
do we need any inspect icmp on this router also ? or any policy modification to pass traffic across the interfac on router is required ?
I was useinf c2900k9-15.0(M4).bin and i upgraded it to 15.3 which is lated to get reed of any bug .
I connected two laptops directly to router's gi0/0, g0/1 interface to ping from one laptop to another but this also did not work.

Cisco Firewall :: ASA 5520 Not Passing Full Interface Rate Traffic

Apr 12, 2012

I have an issue where our ASA 5520 is impacting upload (from LAN to internet) speed. We have a 100Mbps SDSL internet link and only see around 45-50 Mbps on the upload when going via the firewall, download is around 90+ Mbps so that is acceptable. I have tested a laptop connected directly to the internet router and that give near on the 100Mbps up and down speeds, but if I put that laptop on the LAN or directly onto the firewall interface I only see 90Mbps down and 45Mbps up. I have check that the interface speeds/duplex on the firewall, switch and laptop are correct and also checked there are no errors on the ports. I also turned off the IPS and that made no difference. In addition I have checked the CPU during download/upload (max): CPU utilization for 5 seconds = 9%; 1 minute: 3%; 5 minutes: 1%
In theory the 5520 should be able to cope with this throughput:

Cisco ASA 5500 Series Model/License:    5520
Maximum firewall throughput (Mbps):          450 Mbps
Maximum firewall connections:                      280,000

Cisco WAN :: 2821 - Lost Traffic When Multilink Drops T1

Feb 14, 2012

MPLS customer with 4 T1s in a multilink. If one of the T1s drops there is a brief delay in traffic picking back up and I actually lose packets from premise back to CO. You can see this loss both with pinging across the circuit and with techs on either end running JPerf. It can take as long as 6 seconds for the reconvergence to actually happen on the multilink and traffic picks back up. In my experience this is normal behavior for Mulitlinks

I'd also like to note that it is indeed much quicker reconvergence when you physically pull the T1, any of the T1s, rather than administratively shutting down one of them and I understand that the hardware is quicker than software and that's a good thing, obviously. I've tried this with and without ppp mulitlink fragment disabled on either end and every other combo between the two. Each of the 4 serial interfaces are on line timing and I tried free-running just on the off chance that it could imrpove the loss, but it gets worse.....back to line timing. I've even tried this on other CPE platforms like two different versions of Adtran CPEs and I get the same thing. Currently I have a new 2821 CPE in place and still get the same thing. Still see a brief amount of traffic loss up to 6-7 seconds or so at times.

Cisco WAN :: 2821 / Netflow Not Working On Multilink Interface

Feb 18, 2013

I have a Cisco 2821 with two serial interfaces bundled using PPP multilink. I want to monitor traffic flow (net flow) on the multilink interface. I have tried configuring ip route-cache flow/ ip flow ingress / egress but no luck.The other thing is when I do sh ip cache flow I guess I should see the multilink interface in both Source and destination columns which is not happening (not showing in destination column).The other router with same config but with ATM sub-interface working properly (same IOS). Are there any hits on this ? Also, is it possible to use SPAN feature ? The monitoring server is at some other site (coming via WAN).

Cisco WAN :: 3845 - How To Create Multilink Interface And Assign IP

Oct 16, 2011

I have a question regarding mlppp and bonding mpls T1 circuits.   For the longest time we have been able to get by on one T1 circuit coming into our 3845 router. Well this T1 has now become congested and they are wanting to add bandwidth to this T1.   We connect to the phone company via an MPLS T1 currently. So now it appears as though we are going to purchase another MPLS T1 circuit and bond the two T1's together. The way our network is currently set up, we utilize the same AS number on all of our remote routers regardless of location.  Keep in mind I don't have any sort of mlppp set up at this moment, so unfortunately I can't post any configs.  I'm just questioning the design portion and how to go about doing this.
Here is where my dilemma begins........
For every MPLS circuit we order on the remote end, we specifiy an IP for the remote router itself and one for the provider to assign to their equipment (the bgp neighbor statements).   Now granted i'm no BGP extraordinaire, not even a novice really, but I don't understand how I am going to bring two T1 circuits into the same router (basically with 2 pairs of IP's).   In order to bond the two T1's together, i'll need to create a multilink interface and assign an IP to that, but yet I still have 2 SETS of ip addresses. And if that isn't enough of a dilemma, I also need to spedify a neighbor statement in order for my AS to bind to the adjacent provider AS, but yet I have two IP addresses for that as well.

We found out that only local multicast ip address range is not passing between the sites, any other range is passing, local range is and above.
We have two different datacenters, the internal switch is 2960S (Stacked) with 1-10 vlans and the external switch is 3560E, the external switch is adding another tag (qinq, dot1q), vlan 611, and send the packets to metro line to the other site.
on the other site we have the same configuration.
internal switch from site A is configured with igmp querier and the internal switch port on site B connected to the external switch is configured as mrotuer port.
multicast and igmp is passig between the sites, but the local multicast range is not passing, igmp filterring is configured on all port but no profile is defined and no ports are filterred, on the external switch igmp snooping is disabled.

Cisco Switching/Routing :: PPP Multilink Not Coming Up On Serial Interface / 3620 Router?

Nov 1, 2011

I just finished setting up a bundle of (2) T1's in a multilink bundle and I'm having issues with one of the T1's not wanting to join the bundle.
The router I'm using on the remote office location is a 3620 router running code c3620-i-mz.121-1c.bin
The campus router which is a 7206 is setup the same exact way with multilink 240 and like I've said, serial 0/0 is joined to the bundle just fine, so we are running off one T1 connection.
The serial interface that is not working is: serial 0/1

Cisco VPN :: 871 Passing Traffic Between Two VPN Devices Within A LAN

Sep 21, 2012

I have a vendor that currently uses a Cisco 871 as a VPN router in our company network, they use it connect to provide services to one of the servers in our LAN for our customers. Recently, we are going to be setting up a 24/7 call center with this vendor, they will be accessing a server in our network through the VPN to provide customer service during after hour periods.We have a problem however, with an application that is hosted by another vendor that is critical for our regular company call center. Access is reached with this application through this vendor by way of IPSec VPN tunnel that is built in our company's Cisco ASA 5510. This application is accessed via Internet Explorer that goes across to access the application at the endpoint
I need to figure a way by which the vendor that will be running the 24/7 call center coming through their tunnel in our network to connect over to the tunnel on the vendor on my ASA. Im likely going to have to set some routing of traffic in my internal default gateway router for this to work.

Cisco VPN :: Traffic Not Passing Through On ASA 5505

Sep 7, 2011

I've got a client that recently got an ASA 5505. E0/0 is connected to the outside, E0/1 connected to the internal server (Win 2008). The ASA "local network" is; my internal network is I'm able to connect from home through AnyConnect and get a proper address (which I've got a pool of assigned for VPN users), but no traffic from my computer will go to the internal network, nor will the internal server (or the ASA for that matter) can't talk to my VPN'd computer.

On the firewall settings on the ASA, I've got it all open: any/any on both inside and outside, just to try and get anything to go through. I've even got split-tunneling working, but not traffic-passing! The config is below (redacting local AAA users).

Cisco VPN :: 5520 - Tunnel Up But Not Passing Traffic

Jan 15, 2012

I have a site to site tunnel between two 5520 ASAs.  Tunnel is up but when I try to talk to the other side, the implicit deny on the inside interface of the local ASA blocks the traffic.  When I ping, the tunnel comes up but in the logs it says it is blocking icmp from inside to outside.  I have tried the sys opt connection permit-vpn but it is not working.  The traffic is from 5 specific machines within the local sub net that I put in a network object group called Celerra_Replication.

I want to them to be able to talk to 5 machines on the far end of the tunnel in a seperate sub net.  They are in a net wrok object group called GP_Celerra_Replication The ACLs I created for this appear to be created correctly allowing IP from Celerra_replication to GP_Celerra_Replication and the opposite on the other side.

D-Link DIR-655 :: Passing SQL Server Traffic?

Jan 24, 2012

I have a server with SQL Server 2008 on it.  It listens on the default ports 1433 & 1434.  But traffic is not making it through my DIR-655 to the LAN so that SQL Server can respond to the request.  I am using DynDNS and have confirmed that the traffic is getting thru DNS and finding the router, but after watching the syslog I can see that I'm getting multiple of the following error messages when a request is initiated from a client (Microsoft Access app) outside my network:

01-24-2012   22:28:24   System3.Info   Tue Jan 24 22:28:28 2012 D-Link Systems DIR-655 System Log: Blocked incoming TCP connection request from to 01-24-2012   22:28:24   System3.Info   Tue Jan 24 22:28:28 2012 D-Link Systems DIR-655 System Log: Blocked incoming TCP connection request from to

In Port Forwarding I have specified a rule to allow/pass port 1433 & 1434 TCP traffic to my internal server IP.

Also I'm confused by the ports shown above since I was expecting to see 1433/1434 in there...seems this is a factor in the traffic never getting to the SQL Server to process the request?

Cisco WAN :: 2911 Stops Responding After A Period Of Time

I have a Cisco 2911 router with 4 T1 connections.  Two are set as a multilink and the other two are for two other locations.  The router will run fine, but after a month I cannot ping the gigabit ethernet 0/0 interface.  I would have to manually reboot the router to get it to respond again.  Before I noticed a lot of interface discards which would shutdown the 2911 and a manual reboot would be needed, but for this time it isn't the case.  Where would I start with this the memory and cpu usage are fine.
Here is the config:

Cisco Firewall :: Passing Traffic From Polycom Via 1812

Jun 15, 2011

We are trying to get a video conference system (POLYCOM) up running.  Thrue a Cisco 1812 router with Firewall feature set.
I  Have heard in the past that there should be issues with Polycom and Cisco, but have actually never seen it.I can establish a video call from inside the 1812 to outside.
But when I try from outside to the public ip adress there is nattet to, then it reach the video system and die straight after, so there is never any video session set up.
I have tried to remove everything regarding firewall feature and passing true, so the only thing the 1812 should do is NAT. And still the same.
I can not see anything in the log on the router from the ACL's where I permittet everything, other then it connect on the port TCP 1720, as it should. This is the software I'm running on the router:
Cisco IOS Software, C181X Software (C181X-ADVIPSERVICESK9-M), Version 12.4(15)T3, RELEASE SOFTWARE (fc1)
When I search Google, it look like there is a lot issues with Cisco and Polycom, but I have not found any concret solution. Other then I should use a ADSL line with a public IP address.  As we probably is going to do.

Cisco WAN :: Linux Not Passing Traffic Through 1721 / 1841?

Jan 6, 2011

I run a network that uses MPLS circuits to connect all of the companies different stores.  Internet access is through a Cisco ASA5500 here at the corp headquarters.
To make all of this work, we use a little 1721 gateway router to move traffic as needed.   All the clients in our corporate office use (Cisco 1721) as a gateway.  The 1721 routes the traffic either to the internet ( Cisco ASA5500) or the MPLS router (
For some reason, anything that runs on Linux (Ubuntu server, ReadyNAS boxes, Thecus NAS) will not pass traffic beyond the 1721 gateway router.
I've poured over the config for that router, and I can't find anything that could be causing this not to work.  Thinking that the 1721 was bad, I put an 1841 online in it's place, and it did the same thing.   I'm a noob when it comes to Cisco configs, but am learning as I go along.
Ive attached a txt file of the 1721 config.

Mar 7, 2013

Beta Firmware:
Web server log showing the issue:
2013-03-08 05:39:21 POST /somewebpage/somefile.htm - 80 - - 404 0 0 6098 410 457
ISSUE: 100% of the traffic forwarded through the router is taking on the IP address of the router when it arrives at the web server. In this case,
My email server and FTP servers are having fits due to the anti-hammering issue that this creates.
I simply got the run around and they told me to call level 2 support and did not provide me with a contact number. For some reason, he refused to escalate the call. They simply told me to contact someone from a previous issue in which they gave me the beta firmware to download and I spent a lot of time on the phone to get that far. I do NOT want to speak with the same person who addressed my last issue.

Cisco VPN :: Traffic Is Not Passing On Plain IPSec Tunnel Between Two 892s

Dec 14, 2011

I've replaced real networkID to the one mentined below.
Topology: classical IPSec VPN tunnel between two Cisco 892s, with pre-shared key and no GRE. One 892 (branch_892) has access to the Internet via PPPoE and has three networks/vlans behind it. One VLAN is NATed to access internet via the PPPoE. Access to two other VLANs - VL92 ( and VL93 ( need is done thrue the VPN tunnel.
Second 892 (892_DC) has just one interface - WAN on Gigabit enabled/connected and has a static route to the default GW. It does not have any interal network defined. So the router is strictly used to send traffic for VL92/VL93 to the branch 892 via IPSec tunnel.
Here is the problem: access to/from VL93 ( works, however for VL92 ( - does not.
From devices in VL92 I can ping the 892_DC IP address across the VPN tunnel. From the 892_DC router I can also ping devices in VL92. However I can no ping from VL92 any device beyond the 892_DC and at the same time packet arriving on 892_DC for VL92 are not sent out via the VPN tunnel.
I took the packet trace on 892_DC using capture point/buffer to capute packets for VL92 and could see that traffic does arrive at the 892_DC. I run the same capute on Branch_892 and there was not a single packet.More interesting I modified the access list such a way that left on VL92 and still - no packets are sent out thru the tunnel.
