What VPN protocol does the dial-up user try to use over their TCP/IP connection when connecting to the RAS server? IPSec? PPTP? Or should I say in MicrosoftSpeak ... What VPN protocol does the "connectoid" on the client try and use to connect to the RAS? [yuk]. A start on this might be to identify whether or not your remote workstations are using the built-in Microsoft VPN/dial-up/whatever client, and what OS they are running. Once you know what protocol they are trying to use, then you can find out why the firewall is stopping the communication. If you don't know what protocol the clients are using then the ports on the firewall might be closed to that protocol, or the NAT could be "corrupting" the VPN traffic (from the VPN's software's point-of-view), assuming that the firewall is acting as a firewalls generally do.
