Hi there. I'm having trouble with getting multiple users to connect to a remote server via VPN at the same time.
I have a remote Windows Server 2003 SBS system with a PPTP VPN setup. I have 4 users in the an office behind the same router that need to access the server.
What's happening is that I can get one machine to connect with no problems at all. Anyone else is getting "Error 721 - Remote computer is not responding." If I disconnect the first computer, I still can't login with any of the others, but I can relogin with the first with no trouble.
If I reset the router on our side, which is an Actiontec GT701-WG, I can then login using one of the other machines, but again, I can't login with any of the remaining three. Even the one that was working last time.
What's odd is that when I set this up two days ago, I'm sure I had at least 2 or 3 of the machines running at the same time. I certainly wasn't rebooting the router between machines.
In digging around and on this site, I saw some indication that you can't create multiple PPTP connections if you have only one public IP on each side. Is this so? Is that my problem? If it is, how come it was working two days ago? How can I resolve this?
I'll be keeping a close eye on this topic tonight so hopefully some people smarter than I am are up late and bored.
Thanks for your help.
