The VPN server runs on the firewall machine and the VPN client runs on a W2K machine behind the firewall. The VPN

I''ve set the apropriate ACCEPT rules to allow tcp port 1723 and protocol 47 to the host

Last question, I promise, I am running PopTop for PPTP on the same box as my firewall. I can connect to the box fine, but nothing will route between the VPN tunnel and the local hosts.
