Hi All,

we need to replace our TMG 2010 internal and public IP addresses due to network segment change,

will i need to re-install the TMG software? where will i need to change the IP addresses except to the NIC settings? 

can you please advise what is the best way to do it?

Thanks in advance,

You don't mention what you have configured on your TMG but this is basically how you do it:

Before doing anything, backup the server and export the TMG configuration. Do this while physically logged on to the server.

Change the external IP first.

- change IP address on ext nic through Getting Started Wizard, apply the settings

- change any server publishing rules and web listeners that are using a specified IP address

When done and all is verified to be working, move on to the internal ip address.

- Change the IP address from within the Gestting Started Wizard. Apply the settings

- validate all network objects and update the ones that need to be updated with a correct IP address. Don't forget to look at the system policy as well.

You may need to alter the SQL configuration as well:

SQL Server Configuration Manager / SQL Server Network Configuration / Protocols for MSFW/ISARS / TCP/IP / IP Addresses (most likely only ISARS)
