I have a user that can not access our VPN server. We are just using a Windows 2003 server with routing and remote access. All users connect with PPTP VPN. Our router is a linksys RV082 with PPTP passthrough enabled and port 1723 forwarded to the server. Everyone can access the VPN server with no problems except for this one user. Now on the user's end he does have a firewall, I think just a linksys wrt54g. We did try taking his home firewall out of the picture, it made no difference. Also he can connect to other VPN network with no issues. One thing I had tried to resolve this was just reset power on our firewall in the office, after I did that he could actually connect with VPN and we though everything was good to go, but then a couple days ago this happened again, and this time reseting the firewall did not fix it. So does anyone have any idea what could cause this?
