A am wondering how this solution should work as only configuration data of the send connectors are part of edge sync data, look at
http://technet.microsoft.com/en-us/library/bb232177.aspx
Receive Connector configuration is not affected by edge sync. I would be curios if the additional ip-address of the receive connector is still there after a reboot of TMG.
I am looking for an answer.
Best regards
