Cisco IOS VPN unable to route to multiple internal subnets

Unanswered Question
Jul 15th, 2008

I am trying to setup a VPN router using a 3640 with dual FE interfaces. Attached is my config.

I can ping and attach to anything on the network. All the others I can not even ping from the remote users via VPN.

I am using the MS VPN client in XP. If I set the TCP/IP settings on the client to use the default gateway on the remote network, then it does try to route there. Unfortunately, I do not want to cause any PC related routing issues as this will be used by remote support people to get to servers.

I know I am missing something simple. It just hasn't slapped me in the face yet.

Also any suggestions to make it cleaner, please feel free.

I have this problem too.

Try giving specific IP address in the secondary IP's

no ip address secondary

ip address secondary

I realized that I had a typo there, and corrected it and forgot to update the info I posted here.

That did not work.

Is the only way to make this work to use the default gateway on the remote network? If it is was a site to site vpn, it would be easy to route the traffic.

Would it work if I turned on RIP in the config on the 3640? I can diable it on the public interface and leave it for internal only.
