We have two BEFSX41s and two BEFVP41s, I have attempted to setup a stable VPN from one location to the other. It appears that I get a connection. It appears from the log file that a tunnel is reestablished approx every 3 or 4 minutes. I have tried SX to SX and VP to VP with the same results, I installed Wallwatcher to see if I could determine what is causing the problem. Does anyone have any suggestions??? Is there a good source of info on how to interpret the log messages?
