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 snorri788,

Based on my research, I know that When EdgeSync is enabled you cant make direct changes on some properties of the Exchange Edge and should do it via Exchange Hub Transport Server. 

More information, please refer following blog:

Unable to Add an Additional IP on Receive Connector on Exchange Edge when using E-Mail Protection feature on Forefront TMG 2010

Thanks

Mavis,

I found that the solution was to do turn off email integration by following these steps:

After doing that, I could change the settings in the Exchange Management Console on the Edge without the settings being overwritten.
