The default gateway used by the Symantec Messaging Gateway (SMG) needs to be temporarily changed using the command line interface (CLI).

Messaging Gateway

• Check the current IP routing table with the command:
  route -n
   
• To add the new default gateway to be used:
  route add default gw #.#.#.# (where #.#.#.# is new default gateway IP)
   
• If another gateway route previously existed, you may delete it by issuing the command::
  route del default gw 192.0.2.1 (where 192.0.2.1 is old IP gateway)

Note: This is not a permanent change. You must also change the netword configuration for the scanner in the Control Center Administration > Configuration > host > Ethernet to make the change permanent.
