I have confuigured a VPN tunnel site to site between two sites on different subnets.
Now from site B I can ping, rdp etc to any servers at site A. BUT.... the other direction I cant ping site B from site A or connect to anything on the B subnet.
If I try a ping to Site B subnet it reaches the router, it then seems to go to a 172.x.x.x address?
...which replied to say cant contact the network.
it looks like its getting past the firewall /router at site A as a 172 address is replying to say cant find the host...?
I checked all the settings on the firewall at A and I cant see any difference between another VPN we have setup for something else...
What should I be checking?
