I am using 3 WRV54g (rev.2 firmware 2.37.1) routers at 3 different locations. All three locations have static (wan) ip addresses on Verizon DSL using Westell wirespeed modems. The VPN settings are as listed below. The problem is the application that I use requires constant connection to the server (15 second update interval). When the VPN drops the application throws XP into a hissy fit. The symptoms are: 1. VPN seems to disconnect on one end only. (I can quick vpn into one end and see the tunnel is "connected"). 2. Cannot use quick VPN to connect remotely. 3. Cannot login to the GUI locally (Page not found) 4. Only fix I can find is a reboot of the router. Once I reboot, the remote access, local access and VPN tunnel all come back. Doesn't seem like a big deal except for the fact that it takes me 3 to 4 minutes of phone work to get the employees running the application again, ie ctrl, alt, del > task manager, etc. Here's the tunnel details. Any help would be great. Thanks...

Thanks again in advance for any help.
