Cisco WAN :: 3825 Router Interface Does Not Pass Traffic
Mar 7, 2012
we have a Cisco 3825 router which does not work well with a DSL modem(ISP provided). I have configured the Gi0/0 port of the router to plug into this DSL modem but it does not ping to the ISP gateway. If we do a shut/no shut on the interface then it work fine for about 30 secs. Sometimes even for 1 hr. Then the packets drop and we cannot pass any traffic through this interface.
Now, if the ISP connection is terminated on a computer it works fine. It works fine without dropping any packet.I have tried various options like using a straight/cross cable. I have tried to configure the interface negotiation for 100/full, 100/half, auto/auto and almost all the options.I have also tried to interconnect the devices using a L2 device like a HUB. Nothing works.

I have my main branch router (3825) and two remote routers (2821's). They are connected through leased lines that do not touch the internet. For various security reasons I have to ensure that the traffic from the remote's are encrypted in a VPN tunnel even though it is still part of a private network.I have went ahead and created the tunnels and I can verify that they are up. I have applied the cryptomap to the correct interfaces, etc.So the question is - How do I ensure that traffic is not just being router out of the interface from the remote sites back to the branch router with or without using the VPN tunnel? I've taken down the tunnels and of course, the traffic is still being passed back and fourth.

A PC connected to a Cisco 877 router and 877 router is connected to another router (7301) via GRE tunnel,Cisco 7301 router is a NAS server and is being used as a PPPOE server.If user create a PPPOE connection on his computer and dial with a username/pass we want to send the PPPOE traffic to 7301 router, so 877 router should pass the PPPOE traffic to 7301 and user will be able to connect,User -> 877 -> 7301(PPPOE server).

I recently upgraded from a Cisco 3900 series router to a Cisco ASR1k router. Since the upgrade, I have internal clients who claim they cannot connect to external VPNs. These internal clients are behind a NAT that routes a public IP address to a group of clients with private IP addresses.
How can I ensure that all VPN traffic is able to pass through the NAT?

I cannot telent to 1941 router from a Window 7 PC and I can a Window XP PC. Telnet is enabled on Win 7 PC. I upgraded 1941 to latest IOS.Compters running Windows XP can telnet to router and hit the internet. Computers running Windows 7 cannot hit the internet. I replaced the 1941 with a 1760 router and Win 7 computers can telnet to router and hit the internet. I used the same config from the 1941 on the 1760.

I have two 3825's. Each has it's own ISP connection. Nat is configued for both. They have an ethernet connection between them and I'm running OSPF between the two so the routes propogate. I have qty 11 Dialer interfaces configured on each router (each router has an exact copy of the other routers dialer interface). However, I only want the Dialers up if the ISP connection on the mated router goes down. Much like HSRP I need one to preempt and be active if both ISP connections are up. When one goes down the other Dialers must come up. Each dialer sends a Dynamic DNS host name and IP address pair to DynDNS.org. So I cannot have both up otherwise the DNS names will bounce between ISP#1's IP address and ISP#2's IP address (back and forth). Let me know if any option exists to make this happen. As an aside the ISP's are providing me DHCP addresses so I cannot work off of an IP, it has to be the physical interface (i.e. Gi0/0).

A former coworker of mine setup VPN capabilities to our office network shortly before he left. It is no longer working. We can connect to VPN but I'm not able to ping any devices on the remote network or Remote Desktop to any of the server. After 30 minutes, the VPN connection drops. I have attached our ASA 5505 config to assist in troubleshooting.

I can telnet to the router and ping places on the inside and outside. However when I connect a laptop to the inside interface I can ping to the outside for a bit but can't open a web page and then connectivity is gone all together. At first I thought it was a NAT issue but I know I am good on that front. I have attempted to change the speeds and duplex settings on the outside interface but it does not seem to work. Again if I take the cable from the outside interface and plug it into a laptop it works fine. The thing that makes me wonder is why can I connect to the outside interface and configure it just fine?

I'm fairly new to Cisco products am in the process of developing my network knowledge on a deeper level. I have a 3825 with a HWIC-4ESW and I'm struggling to fully understand how the two "see" each other. I've setup a V LAN with a layer 3 address on the HWIC and added the switch ports to it. This seemed to allow devices connected to the switch ports to talk to the built-in router ports. I thought this was all making sense until i applied an access-list to the router port. It's a simple ACL i'm just using for testing and the only thing it does is blocks telnet from anywhere. I know the ACL is setup properly because if I connect a device directly to the router port i cannot telnet to the port. However, if i connect a device to one of the switch ports, i am able to telnet to the router port successfully.
It seems that I'm missing something with how traffic flows from the switch port to the router ports and how the two "see" each other.

I used the GUI configuration tool for this ASA 5505. When I install it no traffic passes. I am wondering to verify my config. I have masked the usernames for VPN with xxxxxx and yyyyyy. [code]

I am trying to setup my very first ASA5505 and I cannot get it to pass traffic from the inside to the outside. I am not using NAT/PAT. Here is what I have done so far.
ASA5505(config)# interface Vlan 1ASA5505(config-if)# nameif insideASA5505(config-if)# security-level 100ASA5505(config-if)# ip address 33.46.132.34 255.255.255.248ASA5505(config-if)# no shut
[Code]....
Then from the asdm I permited everything from inside to go out but I cannot get any traffic through. I can ping the outside if I source the outside interface but not if I source the inside. The logs would not show me anything.
I did a packet tracer and it indicates the implicit deny rule at the end of the access-list is stopping my traffic eventhough I have allow rules above it?
I also checked the box in the asdm to allow traffic to pass without NAT

i read cisco document:[URL] pptp client is in inside,pptp server is in outside.when i donot use firewall, the pptp connection can establish successfully.but use pix 525 7.0(7) i config:
inspect pptp.
pptp connection cannot setup.
show connection in pix:
pptp tcp 1723 is ok.
gre connection only one "E" flag, E means 'outside back connection'.i try second method:delete 'inspect pptp',permit tcp 1723 and gre traffic from outside to inside, and i have config static nat,but the pptp connection cannot work too.so i think there is a pptp bug exist in pix 7.0(7).

I have a 3825 with a 1Gb fiber card at one of my sites. Our ISP and MPLS provider hand off a single gigabit fiber to us that contains 2 50MB EVC's.I need to apply QoS to one of the EVC's and shape them both to 50Mb to avoid upstream rate mismatch bottlenecks. Both of the EVC's generally only push 10Mb during business hours.When I run UDP stream tests (various rates from 500k-6m that are marked as AF41) to one of my other sites I am consistently getting about 2% packet loss, despite the fact the circuit isn't even close to 50% saturation. When I remove Shaping and QoS all together, the issue nearly clears itself up, except during peak hours and I get small bursts of packet loss, which is still unacceptable.When the pipe is at near zero utilization (after hours) there also is no packet loss with or with out the shaping/qos applied.

I have a trouble with Cisco ASA 5510. I configured an SSL VPN with bookmarks to some application. When the users make access to the Web Portal they have to login twice: one for enter in the SSL and one for enter in the application.
How to bypass double authentication?

I am trying to use a ASA 5510 with AnyConnect as an in-line SSL VPN device. I have a separate firewall that NAT's 443 to the inside IP of the ASA, which is the only configured interface on the ASA. I can connect to the ASA from the WAN just fine and the AnyConnect client connects just fine, I get an IP lease across the VPN on my LAN, all looks well. The problem is that I cannot pass any traffic. The only device on my LAN that I can ping is the ASA, nothing else including the default gateway is accessibe. I have setup a static route on the ASA pointing 0.0.0.0 0.0.0.0 to the LAN gateway, but no dice.

We have an issue where by we connect to various customers and the Cisco IPSEC remote access works fine from our LAN through an ASA5505 to a customer site.We have 1 customer that we have some issues with. We can connect from the LAN through to the customers VPN, authenticate and establish a tunnel but in we cannot pass traffic. When we try from outside of the office on a public internet connection the VPN works fine. What could cause this issue?

I have a 7206 VXR router between a several Mikrotik routers on our backbone. We have the Mikrotiks on both sides of the CIsco 7206VXR setup for MPLS/VPLS. I need to simply setup the 7206 to pass the MPLS/VPLS tagged packets to the next router on the link. We are using OSPF as the routing protocol. I am told by our Mikrotik guy that I just need to enable LDP and VPLS tunnels 4:0 on the 2 gig interfaces on the 7206VXR to let it pass the MPLS/VPLS traffic. It sounds simple but I'm not sure how to do this.
Any commands I need to imput to allow this router to pass this MPLS/VPLS traffic.

[OK] Site to Site IPSec + GRE = success, no problems.
[OK] IPSec remote access = success, no problems.
[NO] SSL VPN = remote users can successfully connect to all internal systems. Cannot pass traffic to the Internet.
Hardware:
Cisco 2811, Cisco IOS Software, 2800 Software (C2800NM-ADVIPSERVICESK9-M), Version 12.4(22)T5, RELEASE SOFTWARE (fc3) . Software: Cisco Any Connect Secure Mobility Version 3.1.01065
Single hub router terminating IPSec+GRE site to site, IPSec remote access, and SSLVPN remote access VPN services. All services currently configured and running successfully with the exception of the SSLVPN service. Remote users can initiate and successfully establish SSL VPN sessions. While established, connectivity to all internal systems/resources are successful. Only when the remote access client tries to connect to "Outside" Internet resources does traffic not pass successfully. Troubleshooting has pointed to a NAT related issue (I believe).
When connecting from a remote access workstation, utilizing IPSec remote access client (built-in Cisco IPSec client from Mac OS), the session establishes and the client works flawlessly. Examining the Cisco 2811 router, you see the /32 host route from the remote access session get installed, and you see the corresponding NAT translation entries created when the client accesses outside (Internet) resources. Appropriate configuration to implement "hair pinning" have been included to handle the in and right back out (with NAT translation) needed for remote clients to access the Internet.
Configured the 2811 for SSL VPN, and remote access clients can successfully connect and access all internal network resources. Examining the Cisco 2811, the /32 host route for the remote access client is installed, pointing to SSLVPN-VIF0 interface with a next hop of 0.0.0.0 When checking the NAT translation table, there are NO entries for the remote access client address created which leads me to believe the hair pinning/NAT function is not being invoked for SSLVPN clients.
Originally, the IPSec remote access VPN local pool was 10.0.100.0 /24. To keep from having to adjust the existing NAT translation, PBR Route-MAP for the hair pinning function - I took the 10.0.100./24 and broke it into a pair of /25 networks. Bottom half for the IPSec remote access VPN pool (10.0.100.0 /25); upper half for the SSL VPN pool (10.0.100.128 /25). By utilizing SSL VPN, is the traffic somehow bypassing the DIALER1 interface where both the crypto map (and more importantly: IP NAT OUTSIDE, and PBR configuration for the hair pinning function)? I cant explain why NAT translation entries are not being created for SSLVPN client sessions.
Cisco 2811 Configuration has been included. IPSec & SSL VPN Remote Access Sessions Captures (performed from same remote client) have been included.

We have a new 100MB internet service, but we only pay for 10MB and above that is a per/MB fee and not cheap. I want to limit all traffic inbound and outbound only to use up to 10MB on the outside interface of our Cisco 3825.

We have a small cisco 1800 series workgroup router that seperates our network from the outside world. The data coming into our network goes into the router on interface fa0/1 and comes out on interface fa0/0. fa0/0 is split into 2 sub-interfaces (fa0/0.2 and 0/0.3). These sub-interfaces correspond to a desktop and server vlan on our network. The workgroup router is connected to a 3560G trunk port (we'll call it switch 1) and switch 1 connects to another 3560G (we'll call it switch 2). Recently I was asked to add another layer of security to our network by installing an ASA 5510 firewall and forcing certain types of traffic to authenticate using their domain credentials for our network. The firewall was set up between the router and switch 1 in transparent, multi-context mode. There are 2 security contexts, 1 for the desktop vlan and 1 for the server. Both have the same security settings applied to them since we want the same behavior regardless of whether they are trying to access the servers or the workstations.

I've just started a CCNA course and my lack of knowledge has me a bit stuck. My network is comprised of Cisco components and I'm semi familiar with them just from reading and looking through options. I currently am using a Cisco ASA 5520 on my network and I am trying to join another network via one of the interfaces. My network is 192.168.0.0 255.255.0.0 and my inside interface is 192.168.1.1 255.255.0.0. I enabled a second interface using a static ip of 10.0.0.1 with a subnet of 255.255.255.128. Connected to that interface, I have a Fortigate firewall at 10.0.0.2 255.255.255.128. I can ping just fine from the Fortigate network to the 10.0.0.1 interface on the Cisco ASA 5520 network, but I can not ping the 10.0.0.1 interface (or anything past it) on the ASA 5520 from any computer on the Cisco network. I've read that ACL's and NAT have to be done as well as enabling traffic between interfaces with the same security levels. (both interfaces have security levels of 100 and the option is checked to allow traffic).
Note: each network has it's own internet connection. The connection is to share information on servers on both networks with each other.
