If you’re an old ISA firewall fan, you know that the default IP address used on the external interface of the ISA firewall was always (well, almost always) the primary IP address on the external interface.
You’d figure that it would be the same on the TMG firewall, right? Wrong. They changed how the IP address on the external interface default is defined.
Check the TMG firewall team blog for details.
