I have a VPN connection setup on a Windows XP Pro machine. Norton Internet Security is disabled and the firewall on my Linksys WRT54G router is disabled. I have PPTP enabled on the router and I even setup the XP machine in a DMZ. The router has the latest firmware. Port 1723 has been forwarded correctly.
When I try to connect to the VPN from any computer, it says "Authenticating Username and Password" but then fails and gives an error "Could not find remote computer".
The only thing I can think of is that the ISP's (Networktel) router has protocl 47 blocked? I call and asked them if I had everything I needed open in order to setup a VPN and they said yes. I am try calling them again and directly asking them about 47.
BTW, the XP machine only has one network card. I have been able to access the VPN within the LAN and it works fine, just not through the WAN.
Any ideas?
