Apr 7, 2011I have an GRE Tunnel across my head office and remote site with multiple subnets using cisco 1841 routers.I can ping most of the devices on the remote side, but I can not ping certain devices.These devices respond to ping requests on the local LAN, but not through the WAN link. If I change the IP of device than it start responding. I am using same gateway and mask on these devices.The remote site is running classic STP on switches with distribution switch being the root bridge.

May 30, 2012I am just setting up a simple scenario with a 1841. Server @ 172.31.1.1 cannot ping 172.31.0.254 or 172.31.0.105. It can ping 172.31.1.250. The router can, on the other hand, ping devices on both networks. This is just for testing routing theory so I don't know why hosts on either side of the network cannot ping each other.
I am only using the FastEthernet interfaces on Router 1841.
Cisco Switching/Routing :: 3560G Can Ping Devices In Enterprise LAN But Cannot Ping Interface
Mar 31, 2012I have a new 3560G to set up a small network for a remote site. I configured the vlan and an SVI as the gateway. The switch is also the DHCP server for the LAN. I configured Gi0/2 as L3 port, connecting to the nearest neighbor. My network runs EIGRP so i advertised the routes into the EIGRP process. The switch forms EIGRP neighbors and learns all routes in the enterprise network. The problems I'm having now are: 1. The switch learns all routes in my enterprise LAN and can ping devices in the enterprise LAN, but I can’t ping any interface on the switch from the enterprise LAN. 2.

Dec 12, 2011I set this up and I can ping all the gateways but never the hosts. I was hoping I could make these links between 6500's a mix of L2 and L3. Check it out. They are connected in a linear fashion R1--->R2--->R3. I can ping from R1 to R3's SVI4 gateway but I can never ping a host on that SVI4. I was hoping that I could use the port-channels between 6500's as routed links or as trunk links depending on the type of traffic....thought it would ease the migration. I suppose I could always get rid of the port-channels and just make separate L2 and L3 links between the 6500's.

Mar 1, 2013I had both a Westell 7500 and a Linksys Router working fine and had my 360 setup as an extender for Windows Media Center so I could stream TV, Music, Movies, etc from my desktop to the 360. Then I switched my modem/router out with a Zyxel PH5001Z
So now today I noticed that I can no longer find my desktop through the XBox. I have adjusted my firewall settings on the modem itself, even completely disabling it. UPnP is enabled for the 360 and the device is showing under my device table. At first I wasn't able to ping any network devices but after creating an ICMPv4 Firewall rule it worked fine. I've confirmed the XBox IP Address through Network Map, the Device Table on the modem and through Network Settings on the XBox. I've diabled my modem firewall as well as Windows Firewall, completely and I still can't ping my XBox or set it up as an Extender.
I have the XBox connected wirelessly using WPA2-Personal and it's operating in 802.11g/n mode.

Feb 1, 2013I am putting an pre-labbed DMVPN Hub config onto a production 1841. We had to upgrade the IOS to support protection with NAT so the current IOS we're running is c1841-adventerprisek9-mz.124-25g.bin.I can paste the configuration in fine (via the tunnel interfaces) and the router accepts it however the 'show dmvpn', 'debug dmvpn' and other related commands don't work. I have checked the IOS feature navigator and it definitely shows that DMVPN phase 1 and 2 are supported in this image.

Apr 23, 2013We have a 1841 setup with WAN and LAN subinterfaced(2 WAN connections, 1 internal VLANs) and I am recieving some pretty horrible throughput when traversing the router to the WAN.
I am receiving about 2 MBPS down but around 5 up.Currently there is a ACL on the WAN interface, and as well we are running NAT NVI. It is possible that this might have something to do with it, but I am not sure.
Most of the CPU is going to IP input however I cannot seem to determine the cause. One thing I am thinking is the overload for NVI is using a route-map. Could that cause it to process switch instead of fast/CEF switch?
Cisco WAN :: 1841 / QOS Over IPSEC VPN?
Mar 25, 2011i have 6 sites using tandberg visioconference system, each site have a cisco router 1841 configured with ipsec vpn, i have a 4 conference a week and my bandwidth is 2 meg, and when people are working we have a lot of problems and cut in our visio conference.
I have a big problem, i want to make a high level QOS priority to my TANDBERG visio conference system between my sites, the issues is that there is an IPSEC VPN in my cisco routers between those sites and as i know if the traffic is crypted we can not separate the packets or give higher priority to packets over anothers.
can i mark traffic in the lan interface and and make a high priority befors the packets go through the ipsec tunnel?

Mar 6, 2011OK ran into a little problem with getting this to work. Only group members participate in the encryption process, correct?
I have numerous remotes all coming into one central location. I set up a KS and have currently only 2 of the remote routers set up as GM's, with the intention of the others coming into play as I move forward. Here is basically what I have in my KS and GM's:
KS
crypto isakmp policy 10 encr aes authentication pre-share group 2crypto isakmp key testkey address [code].........
GM's
crypto isakmp policy 10 encr aes authentication pre-share group 2 lifetime [code]....
So I applied the crypto map to the serial interfaces on my routers on either side of the cloud (central-ASR1002 and remote-ISR1841). When I did this, ALL the remotes went down and I'm not sure why. Even the ones that didn't have anything to do with gdoi. Ya, it wasn't good. I thought that only the group members would be affected.
Is it the fact that my acl is encrypting any to any? Surely I don't have to reverse that and have two statements with the same syntax. I'm basically just trying to encrypt all traffic from specific remotes back to the central side. However, I'm trying to do it without taking down the rest of my network .

Cisco WAN :: 5510 / 1841 - New Set Up To Use PBR
Dec 13, 2011Here is my current situation, I have 3 Internet connections as below, at the moment they are terminate into the ASA.
ADSL Modem 1 (routed mode) ADSL Modem 2 (routed mode) Mid band Ethernet Tail (10m/10m)
ASA 5510 LAN Switch
I want to change it to the following, in order to use PBR on the router. ADSL Modem 1 (/29 Ip block) ADSL Modem 2 (/29 ip block) Mid band Ethernet Tail (10m/10m) (/28 block)
Router ASA 5510 LAN Switch
I need your opinion on the following points
1. What is the best suited router considering i have 2 adsl connections and i will need 3 WAN + 1 LAN ports in total.
2. Where should I run the NAT ? on ASA or the router. (I do have around 20 L2L IPSEC VPN tunnel on the ASA). In the new setup I would like to use ADSL 1 for the internet browsing and use ADSL 2 and Ethernet Tail for incoming service (+some outgoing to specific destinations or based on specific services)
3. I have an old 1841 with 2 Ethernet ports, am i better off buying 2 x ADSL2+ cards and use them with expansion slots?
4. Both adsl connections are PPPOA based, Can I put both adsl modems into bridge mode and create pppoa connections on 1841? (I will still have to buy a HWIC 2 ports Ethernet card).
5. Should i go for any of the above options or am i better of buying a new router?
Cisco WAN :: 1841 Not Able To Reboot

Cisco WAN :: 1841 - NAT Configuration
Sep 4, 2011I have a little problem configuring NAT on router 1841, like this is the topology:
WAN (PUBLIC´S ADDRESS) fast0/0 fast0/0/0 PUBLIC´S ADDRESS INSIDE (192.168.1.0/24)
ROUTER ====== X.X.X.X/30============= ROUTER ======== Z.Z.Z.Z/29 ============ SW 3560==============
(ISP) .253 .254 CLIENT . 47 .48
The connection with ISP or Extra net is a metro Ethernet, so the isp gave two ip address to the client: WAN (/30)
LAN (/29) Which be the public addresses to be used by the client if you need to publish any server on the network (like WWW), so they do not have any device that will could do the nat, like an asa or linux server, so the router has to do the Nat, because the SW 3560 does not support this feature.
So... I did the following:
On router 1841:
inter fast 0/0
description WAN
no shut
[ code ]...
I create an interface Blackpool to simulate the LAN connection (192.168.1.0/24)
Inter loopb 0
ip address 192.168.1.254 255.255.255.0
ip nat inside
[ code ] ...
ON SWITCH:
interface vlan 448
description LAN-ME
ip address Z.Z.Z.48 255.255.255.248
no shut
ip route 0.0.0.0 0.0.0.0 Z.Z.Z.47
But if i try to do ping from the ip address 192.168.1.0/24 to any server´s internet the ping fails, but if i do the ping from v LAN 228 the ping is success. I will think that route map could solve the problem.
Cisco :: Browsing Through 1841 Way Too Slow?
Jul 5, 2012I have an 1841 running Advanced Security IOS (12.4(25) I think, have to check when I get home) that I'm using to learn about CBAC and IOS' firewall functionality. Its external interface is connected to my Windstream DSL modem in bridge mode, and the router is doing the PPPoE authentication. It's also doing NAT for my internal network, and is acting as a firewall using CBAC inspect statements and ACLs.
Everything is working at at least a baseline level: the DSL authenticates and connects, and machines on the inside can browse the web. The problem is that browsing to some sites is slow or times out. Not all sites, just some. Latency seems to be okay when doing pings. The problem seems to happen with https connections, but again, not all of them. Gmail works fine (I have it set to always use https), while my bank and credit card sites either time out or take minutes to load.
I have an "inspect https" line in my config, and have allowed https through my outbound ACL.
I'm looking for next steps for troubleshooting this. I've check CPU utilization and it's very low; not sure what else it could be. I only have a few inspect statements, for the common stuff: tcp, udp, icmp, pop3, imap, dns, tftp, ftp, and ntp.
