Hi Colter,
 
Check out my article on setting up an ISA firewall in an ISP like setup.

        Let me give you a little more info as i hope that helps.  I am
setting up a server within a NAT environment.  This server is Windows
2003 with ISA 2000 with hotfix 255.  I have to network interfaces, one
enabled, one disabled.  I only need on interface to work as this machine
is going to be setup to be a commercial webserver.  This webserver will
only have ONE live ip address.  I am setting it up within our NAT
environment to get it ready for deployment.  Once deployed i will change
it to the live IP address.  
         
        During the install of ISA onto the Windows 2003 server i
installed in Firewall Mode (as that is all that is needed to protect the
webserver). When asking me to construct the LAT table i used the
internal IP address that this machine is now, 192.168.1.100 and the
future live IP address it will be.  Routing and Remote access will not
be used on this machine. 
         
        I have completed the full install and based on previous installs
i have worked on ISA installs with all ports closed and i would have to
open them to make them work.  Before I even touch ISA all ports are
open, which means i can connect to lets say Terminal Services even
though i have not made a rule allowing that port to be open.  This shows
me that the Firewall Service isn't even working.  There are no errors in
the event log and I am stumped to why ISA is not working.  Thanks for
the help.
