IPSEC Tunnel Routing question

[Tom Thompson]

Thanks for the reply!

I have tried what you recommended and basically nothing can talk over the vpn tunnels unless it is addressed on Building A or Building B's network. 

I have a router with an internet connection sitting at Building A and I set the defaultrouter in Building B to be the router address.  I can ping the router but the traffic will not even go thru the vpn and I get ping saying the network is down.  

I can post configs if you think it will help

Thanks
Tom
