Cisco IOS VPN unable to route to multiple internal subnets

paarlberg · ‎07-15-2008

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 192.168.40.0/24 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.

What am I missing? Anyone?

Try giving specific IP address in the secondary IP's

no ip address 192.168.41.0 255.255.255.0 secondary

ip address 192.168.41.1 255.255.255.0 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.
