Are there any caveats of which I should be aware before adding additional IP address(es) to the external interface on ISA Server 2006 (running on Windows Server 2003)? The purpose is to bind an additional listener on the IP address (because it needs a different certificate). I have done some research and it seems straightforward, but I am a little uncertain about it. Our setup is pretty straightforward, just the 2 interfaces on the server. Bill Mayo
