I have dozens of Linksys BEFVP41's in the field, all making a VPN connection to a PIX 520. Each router is connecting via some form of Broadband connection. I have a number of routers that randomly have their tunnel drop, requiring a reboot of the linksys, sometimes more than once a day. The SA lifetime I have specified on both the PIX and the Linksys routers is 86400. Linksys told me the max they support is 28800 which I don't believe. Has anyone had something similiar, and found a way to alleviate the tunnel drops?
