Am running 2 computers on a DI 624, one wired, one wireless. When both are connected to VPN (different VPN's at different companies), every 10min or so, both connections drop and we need to reconnect the VPN connection (running XP - and the local LAN connection disconnect message also appears at that time). Have loaded the latest firmware, rebooted the router, still no change. Any suggestions? One VPN connection works fine alll day long.
It sounds like something is wrong with the router. We have the same one here and run multiple VPNs through it all day long. Have you set up the log feature so you can see what is happening when it disconnects? That may help out with figuring out why as well.
