I'm not by any means an ISA expert. I will be in charge of setting up our new network, however. I need a reality check on the setup I'm envisioning. Is this the best way to set things up (if it works at all)?

                        Internet Router
                             ISA machine
                            /               \
                          /                   \
                        /                       \
                Domain1                    Domain2
                (             (

Each domain will have its own domain controller, and the two domains will have two-way trust relationships. I'm looking to set up ISA server to route traffic in these ways:
- From Domain1 to the internet (and vice-versa. domain1 will contain our webserver, so traffic needs to come in)
- From Domain2 to the internet (and vice-versa)
- From Domain1 to Domain2 (and vice-versa)

The ISA machine will have 3 NICs, and we'll have >3 external IP addresses to work with.

I just need to be sure that ISA server can handle this, and maybe some opinions on whether or not this is the best idea.

Thanks in advance, I really appreciate it
