The WAN menu item is used to set Quality of Service parameters for the wide
area network, and to specify the IP address to be used for multicasting internal
messages over the satellite network.

WAN-to-WAN Internal Multicast Address
This multicast address is utilized by the Hub modem units for passing internal
messages to the Remotes. Note that these messages are transmitted only over
the satellite (WAN) network; they are never passed over the LAN.
One example of this feature is the enhanced performance of return path SCPC
switching that results when an assigned Hub expansion unit sends a switching
trigger message to the Remote that has issued the switch request.
OSPF Application
In networks utilizing the OSPF routing protocol, this address serves for the
multicasting of dynamic route changes that are passed from the Hub to all of the
Remotes.
This parameter must be set to the same address for all modem units in the
network. The default setting is 239.30.31.32.
