I'm in the process of setting up ISA server 2k6 on our email relay server (it was in a simple nic bridge). Now I'm going through the documentation I have, and it says enter the WAN info into the external NIC. ^Does that actually work while I'm behind a firewall?
I'll also mention, our hw firewall registers our users dhcp, so there is no option in removing it (plus we just renewed the license for it).
should i just enter wan info into the external nic anyways? or assign a static internal address (meaning external and internal nics both have internal ip's)?
our setup isn't really listed in isa (ie: back-end or front-end, etc). We have our hw firewall, and then isa 2k6 (with relays inbound/outbound email, also runs are gfi suite for email scanning, and we'll need to setup publishing for the owa). I would guess our setup is more like a double front end?
