  1. Remove ether 5 from bridge if it was in.
  2. Replicate all settings of port 1 to port 5.
  3. Remove all settings of port 1 from the configuration.
  4. Check and correct all routes, port lists, firewall rules and other stuff whether it is correct, eventually correct it manually accordingly to your change.
  5. Plug the wire from port 1 to port 5.
