Pptp vpn

[zuixro]

I am running an Xubuntu 9.10 PPTP server. It's all working great except that it isn't routing traffic to the open internet. When I log in, I can ping other clients, but I can't ping "google.com" for example. I've been searching for a very long time, and I can't find anything that's worked. I think it's an iptables entry and a route. I've seen several examples, but none of them have worked for me. Can anybody help?

I really need help if anyone has solved this problem. I have the clients talking to each other, but not to the internet. Could I add an iptables entry that says to allow the ppp interface talk to eth0?
