Site To Site VPN not connecting with other site

jsandau · ‎11-22-2011

I have 2 Cisco routers and I am trying to set up a site to site vpn between them. I go through the wizard in CCP but when I go to test the tunnel I get the following reason for failure on both routers:

"There is no response from the peer *peer ip address*"

Here is the running config from both routers

Cisco Router and Security Device Manager (SDM) is installed on this device.

This feature requires the one-time use of the username "cisco"

with the password "cisco". The default username and password have a privilege level of 15.

Please change these publicly known initial credentials using SDM or the IOS CLI.

Here are the Cisco IOS commands.

username <myuser> privilege 15 secret 0 <mypassword>

no username cisco

Replace <myuser> and <mypassword> with the username and password you want to use.

Router B uses a lot of ACLs so I think the problem may be in there somewhere. I didn't set up Router B, and I'm not too familiar with ACLs. Any Help is greatly appreciated. Thanks.

Actually this is a different site to site issue, then the other one I was having. I solved that one. the subnet of 255.255.0.0 on Vlan1 on router B is correct (as far as I know), because that router have devices attached to it with ip of 10.10.3.3, 10.10.10.2, 10.10.1.1, etc...So, as far as I know, (I didn't set up Router B) the subent of 255.255.0.0 is correct.
