I'm trying to set up a VPN to access my home PC while travelling. Home machine is XP Home with all updates applied. Laptop is XP Pro with all updates applied. I"m on DSL behind a Linksys WRT54G router. Port 1723 is open on the router and firewall. Home machine is configured to accept incoming connections. When trying to connect I get a 721 error while verifying username and password. UltraVNC works just fine but the file transfer has been kinda iffy for me. Any help is greatly appreciated.
