We normally setup VPN’s from WR21’s (remote) to our VC7400 using address (remote) 172.168.x.x/28 to (VC) 0.0.0.0/0  
I need to setup some routers not using the 0.0.0.0/0, say 172.172.x.x/28 to 172.169.x.x/28 (I have set Eth3 to 172.169.0.1/16)  
The tunnel builds and I can ping from the remote to the VC, but cannot go from VC to remote.  
What do I need to set at the VC end? default route or a specific firewall?
