Site to Site VPN Problems

Guest

I'm having some major problems with a site to site vpn. I was able to
successfully set up demand dial connections in both sites and sucessfully
connected. For some reason I can't ping another workstation across sites. I
setup a child domain server on the main site and brought it to the branch
site to be used as the network bridgehead. If I ping from the rras server
itself, I can ping both the Internal address and both demand dial
connections, but it won't ping the internal address of the other router
across the connection. If I try to ping from a workstation, the only thing I
can ping is the ip address of the demand dial connection. Do you think it
could be something to do with the fact that I actually setup the network with
a class B ip addresses. In theory it should all be "one" network . I didn't
use any subnets. One network starts with 172.16.31.x and the other one
starts wtih 172.16.20.x both with a netmask of 255.255.0.0. Please help!!!

Are you using ISA? If so, I had this same problem until I setup an access
rule allowing for traffic to pass over the VPN.

No. I'm just using the standard routing and remote access that came with the
server.

Sounds like routing issue. Posting the results of both server routing tables here may help.
