The SSH session will become non-functional at this point due to the network changes. Also, the GUI should work now only with the new IP address.

6. Navigate to the GUI using the new IP address, and go to Trustwave Devices.

At this point two different IP addresses will show for the device. The old IP address will appear in the Devices tree on the left, and the new IP address will show in the Device IP field on the right:

7. With the IP of the device selected in the tree on the left, click the Edit button in the right pane. Then select the new IP from the Device IP drop down list.

8. Save and commit the changes. The system should update the IP address.
