my question is not direct as i don't know what should i ask to get an answer. i manage verywell my ISA 2004 using 2 NIC (Internal & External). no problems but now this is the case, please try to visualize the case:
I have and ADSL Router for Internet.
Local LAN, and
another LAN behind a frame relay routed path. (branch office).
so i brought this server 2003 machine with ISA 2004 with 3 NICs. 1st is getting the internet from the ADSL router. 2nd is for my LAN (main office LAN) and 3rd is for the Branch office LAN.
Local network ip is 18.104.22.168
Internet IP is (some IP) (Dynamic)
branch network is 172.16.1.0
how should i configure the ISA to allow branch office to access the internet. i would like to add that i configured the ISA once using the edge module and another using the three legged module. please advice.
Note: how can i add an image to this post??? i want to draw and post the toplogy drawing...!

It may be easier to get the two NIC one working first, define the external and the Internal using the template. Once this is done, configure the Branch office, defining an ip range for it also. THen you need to setup relationships between the different networks and what you want to do.
If you require more details then please let me know. I may try and setup a test ISA as i may have missed some steps out as its been a while since i configured one. I'll ask my collegue at work to just run through this also.
