This setting specifies a LAN IP address to be used for accessing administration
functionality. This address should be unique within the LAN.
For Pepwave routers in NAT mode, the virtual IP (VIP) should be set as the default gateway for all
hosts on the LAN segment. For example, a firewall sitting behind the Pepwave router should set its
default gateway as the virtual IP instead of the IP of the master router.
In drop-in mode, no other configuration needs to be set.
