I have a Cisco 515E PIX, with VPN tunnels setup for workers off site. When I run the command sh isakmp sa, I see all of the current connections. Under the column Connection, I will see as many as 1432 connections for a particular IP address. Is this normal, or is it symptomatic of another problem. I noticed that when I have several of these, the connections run slow or stop all together. If this is being caused by a problem, what do I need to do?
