Previously I've been using a windows server to bridge my switches, however, this bridging method has become unstable over time and introduced issues of its own. So I believe I can get greater stability by using TMG as a route (not NAT) between the switches (coming up a level in the OSI model). I've defined a route network rule between the two adapters and created Access Rules for all Protocols between the two networks.

There is one machine (W2K3) on the switch that I'm using for testing and I can see DHCP requests on the TMG log but they are denied, logged with destination being localhost.


Am I in the right direction here? Is there a bridge mode in TMG that I should be using.
