I have a primary static IP and 2 routed IPs coming into my TMG 2010 server. Listeners have been created to handle incoming connections to Exchange 2010 in the internal network. Rules using the listener on the primary IP work as expected. The rules listening on one of the routed IPs seem to be ignored (I see logged traffic that should match the rule but not detected by the rule).
I have manually added the routed IPs to the adapter which establishes the connection to the ISP. These routed IPs have also been added to a new Network in TMG.
Does anyone have any hints on how routed IPs should be configured? Am I missing something simple here?
