a client of mine has a RV042 and uses it to work off site via PPTP server. It all worked fine until Friday, when it all of the sudden started spitting 619 errors saying the port was closed. The client laptop is a Window 7 Pro machine and we use the Windows VPN client to connect. I made no changes to router or client. I disabled the firewall on the client for one connection try, just to make sure and the outcome was the same. The setup of the PPTP server on router and the VPN connection on the client were so simple when I did it initially, that I'm now kinda lost and don't know how to troubleshoot it.
We switched from QuickVPN to PPTP because we had a bunch of issues with QuickVPN and Windows 7 client is much faster.
I'm not sure what I could log to help identify the problem, but I would appreciate a guiding hand I'm going on vacation on Monday and would like to have PPTP running again.
