Just another piece of info for you guys! One thing that I discovered: Imagine we have this scenario: ISA --> DSL Router <---> Internet <--> DSL router -> ISA I created demand-dial interfaces with matching user names at each end. When one end connects, the end automatically connects to the other ISA server. But there's more! One of my ends has a Dynamic IP address. It connects with no secrets! No more Dynamic DNS for me =) The problem with the automatic disconnection at every 3 minutes is gone, too! Woohoo!!
