I have setup a VPN server on a Windows 2003 Server. I only have one network adapter that is connected to my router and then connected to the internet. I setup a client pc (Windows XP) to dial in to the VPN server. I have no problem connecting to the server. However I cannot see any other computers on the server side of the VPN connection. I try to ping another computer but will not see it. I can successfully connect to a share on the server but nothing else. Do I need a NAT or do I need to edit one of the hosts files on the client side? Any help would be appreciated. Thanks.
