I have a PIX 515E connecting to a LANROVER and multiple Linksys VPN devices. The Linksys devices are making mutiple tunnel connections to my PIX. When I do a show isakmp sa, I will see one connection for the lanrover. One connection for a PIX 501 I have somewhere and then for each of the Linksys devices I am seeing upwards of 100 connections. Eventually All tunnels seems to fails and I have to clear isakmp sa and then we are fine for a while.
