I have a LAN setup at my home with windows 2000 server and win2kpro. I have a 4 port linksys router setup with port forwarding to 1723 to my sever. My windows 2000server is setup as a VPN server(routing and remote access). I user verizon DSL. In my local LAN I have no problem using VPN to my server. I went to friends place and dialed-in through AOL and was able to connect to my network. So I know port forwarding is working. When I try from my LAN at work through a T1 line and I get error 721 remote computer not responding. I've tried everything. PLEASE HELP!!!!!!!!!Whats the deal with port 47?
