Hi, I am moving our TMG 2010 server over to a new datacenter and while the IP subnet will be the same the internal IP address of the TMG server must change.

If I understand it right, all I would have to do it change the physical NIC properties to reflect the new address right? If for example I am changing the internal NIC address from 10.0.0.1 to 10.0.0.2 and the 10.0.0.x network is already defined in TMG as an internal network then there is nothing that needs to be done from the TMG point of view correct?  This is not being used as an outgoing web proxy but for server publishing rules.

Am I on the right track?

Thanks for any help.

Hello,

Yes you are right, but sometimes TMG Internal network works in a weired way , so after changing the IP address on physical network do the below

Open TMG management Console.  

Select Networking , then double click on Internal Network to access it's properties.

Switch to Addresses TAB, Select the configured adapter, remove it then re-add it.

iF YOU FACED ANY PROBLEM , RESTART THE SERVICES

PS: Don't forget to change the DNS Record to point to the  new IP
