Can someone clear up a problem I'm having getting my interfaces properly configured to install ISA onto a w2k3 server? I have a dsl connection on my w2k AD home network. ISA will go on a separate w2k3 server that has 2 nics. In following the documentation listed online I have questions on the following: 1. What IP info do I apply to the Nics? The online document lists 123.123.123.170 255.255.255.248 123.123.123.169 for the north. Do I use these same for my north interface or do I use something from my subnet range? I have a dynamic IP so I'm not sure what to use here. 2. What IP info do I apply to my internal nic? I have 192.168.1.50 reserved to this server. Should I change it and go with the 192.168.0.1 255.255.255.0 no gateway? I also have my internal w2k dns and the dns of the ISP that I use for internal name resolution, should I use these here? I know the answers are right there in the documentation I just need confirmation so my apologies for the dumb question. tia
