I have setup a VPN server on Win2K server. It seems to be working fine. I can VPN internally in to the server. However when anyone tries to VPN from the outside, they get stuck at "Verifying User name and Password" screen. After about 20 secondes it errors out (with error #650 on WinME machine).
Company uses Cisco 675 DSL/Router. I have configured the NAT to open 1723 TCP and 47 GRE. I also setup Terminal services and that is working just fine from remote PC's. I'm pretty sure that the problem is not on the server but with the router configuration. I just can't figure out where :(
Has anyone ever ran in to this kind of an issue? Any help would be greatly appreciated! (Company's boss is leaving for vacation on Friday, and he wants to be able to VPN in to his PC at work, so it's kinda urgent that I get it going)
