Warning

Changing the internal or external IP address on a Forefront UAG server is currently an unsupported scenario. The internal and external NICs should be configured before running the Forefront UAG installation. Changing the IP addresses on an operational Forefront UAG server will break the functionality, and is not achievable through the Forefront UAG Management console.
