Hi everyone,
after implementing a ForeFront TMG server I'm facing only one problem:
After I added a second IP to the external adapter I had to manually set "NAT Address Selection" inside the network rule "Internet Access" to the first IP since all others would get blocked by the CISCO firewall.
This configuration works as long as traffic comes from the internal network (e.g. browser on clients). Traffic from the TMG directed to the internet always carries the second IP as it's source address and gets blocked.
All our other TMGs/ISAs are running fine and I never came across this problem-
Does anybody have a clue, coz I don't?!
