I have a 2010 Edge box with TMG installed, and every time I change the IP ranges in the Receive Connector, it gets overwritten by TMG. As a workaround, I can stop the EdgeSync service in TMG and change the individual IP addresses, but I cannot add a range (I want to add a whole subnet).

What if I remove the receive connector completely and replace it with a new one with a different name? Would that still get overwritten by TMG?

Running Forefront TMG 2010 Service Pack 2, Exchange 2010 Service Pack 3 RU4     

Hi,

Please check the thread below.

"When I stop the TMG Control service it does not get overriden, I also read somewhere that you can also disable the TMG / Exchange integration. What I am after is another receive connector on the edge server that will listen on another NIC with different security settings so it can relay mail from the management network - so far only got it to work while the TMG control service is stopped to stop it overriding it."

Joyce,

I have seen this, however do you leave the service stopped simplywhile you make the change, or permanently?

Thanks

This does not work for adding an IP range. You can only add individual hosts using this method.

I found that this is the best solution:
