With PPTP you can not have more than ONE outgoing connection through a NATted connection. If you have (2) XP Machines A and B inside your LAN making the PPTP connection to the remote site, and everything is working OK, the FIRST will work and the second will exhibit the time out issue you explain above. Once the first machine disconnects and the remote PPTP server times out the connection you will be able to connet form a second location from inside your LAN. Is it possible that another machine has opened a PPTP conection to the remote site before you can attempt with your machine? BTW, I experienced this exact problem a while back, but the clients were MAC OSX - The problem is with PPTP and NAT, not XP, or Mac etc... Even if this is not your problem now, it may well become your NEXT problem once you solve whatever is stopping your outgoing PPTP connections (if you have more than one PPTP client behind NAT) Bill Arlofski Chris L. wrote: > Hi Jason, > > Thank you for the reply. > > Some clarifications: > > 1)I'm the admin in both sites. > 2)The VPN I'm trying to access is outside my LAN > (remote location). > 3)Accessing that VPN from elsewhere gives me no > problems at all.
