hey there -
so here is the problem. I have a lan to lan conenction between a remote office and my office. The lan to lan works great between the two networks, illustrated below:

172.16.1.x--concentrator--isp--concentrator--172.31.x.x.

we can pign back and forth, establish connections, etc. The problem arises when trying to talk to the other networks behind the vpn connected networks illustrated below:

172.16.1.x--concentrator--isp--concentrator--172.31.x.x.

10.0.0.x 194.232.1.x

Trying to ping from 10.0.0.x to 172.31.x.x results in a timeout and vice versa. Also, pinging from 194.232.1.x to 172.16.1.x times out as well. I think this is a routing issue (must be) however I can't seem to figure out how to fix it. I thought of nat'ing addresses from the subnets to the vpn nets, but that seemed to me to be overkill. Any advice?

 
Let me first assume that from your internal networks you can reach up to the concentrators.

Then, have you added the internal networks into network list (mentioning which are the remote networks) on LAN-to-LAN connections?

Cheers,
T S
