Poptop server cannot access internal network
I have been banging my head against the wall for about 2 weeks and have searched high and low for an answer to the problem that I seem to be having. I have poptop installed on a debian box and it works perfectly. Except I am unable to access anything beyond the server itself. I have this same configuration setup at three other sites and the same problem exists at all of them. I can create the connection and get connected with no prob but cannot do anything. I am not familiar with ipchains or iptables however I am not sure if that is even what i need to be looking at right now because the linux boxes themselves are not routers, they are behind a router which has the correct ports already forwarded-which is why i am able to make the actual vpn connection. If someone could actually pinpoint why this isnt working I would be so relieved and appreciative. I have tried almost everything that could find to try and I am at a total loss at this point. Thanks in advance.
