Change the IP Addresses of the TMG7800 Telecom Units

Note: For the TMG800 and TMG3200, skip this step.

Before you change the host's subnets, make sure that all the Telecom units of your TMG7800 system have had their IP addresses changed to the new subnet. For each Telecom unit of the TMG7800 system, do the following:

Connect to Telecom unit's shell (using Telnet, or serial port)
Use "set_net" command
Follow the instructions
Reboot the unit

Resetting the Host Role of the Unit

Note: If your Unit was just shipped, it does not have its "role" configured; skip this step.

Changing the internal IP addresses of a TMG requires that the unit's role (Standlone/Primary/Secondary) is reset. Once the role is reset, the Web Portal displays the steps to reconfigure the unit's Role, and configure the internal Subnets.

Make sure to repeat this operation for the two units of your 1+1 system, or the two hosts of your TMG7800 system. In addition, make sure to start with the primary.
