6.5  Configuring WAN MAC
To change your Prestige’s WAN MAC settings, click WAN, then the MAC tab. The screen 
appears as shown.
RIP Version
The RIP Version field controls the format and the broadcasting method of the 
RIP packets that the Prestige sends (it recognizes both formats when 
receiving). 
Choose RIP-1RIP-2B or RIP-2M.
RIP-1 is universally supported; but RIP-2 carries more information. RIP-1 is 
probably adequate for most networks, unless you have an unusual network 
topology. Both RIP-2B and RIP-2M sends the routing data in RIP-2 format; the 
difference being that RIP-2B uses subnet broadcasting while RIP-2M uses 
multicasting. Multicasting can reduce the load on non-router machines since 
they generally do not listen to the RIP multicast address and so will not receive 
the RIP packets. However, if one router uses multicasting, then all routers on 
your network must use multicasting, also. By default, the RIP Version field is 
set to RIP-1.
Multicast
Choose None (default), IGMP-V1 or IGMP-V2. IGMP (Internet Group Multicast 
Protocol) is a network-layer protocol used to establish membership in a 
Multicast group - it is not used to carry user data. IGMP version 2 (RFC 2236) 
is an improvement over version 1 (RFC 1112) but IGMP version 1 is still in 
wide use. If you would like to read more detailed information about 
interoperability between IGMP version 2 and version 1, please see sections 4 
and 5 of RFC 2236.
Windows Networking (NetBIOS over TCP/IP): 
NetBIOS (Network Basic Input/Output System) are TCP or UDP broadcast packets that enable a 
computer to connect to and communicate with a LAN. For some dial-up services such as PPPoE,  
NetBIOS packets cause unwanted calls. However it may sometimes be necessary to allow NetBIOS 
packets to pass through to the WAN in order to find a computer on the WAN.
Allow between LAN 
and WAN
Select this check box to forward NetBIOS packets from the LAN to the WAN 
and from the WAN to the LAN. 
Clear this check box to block all NetBIOS packets going from the LAN to the 
WAN and from the WAN to the LAN.
You also need to configure a firewall rule that allows NetBIOS traffic to pass 
from the WAN to the LAN.
Allow Trigger Dial
Select this option to allow NetBIOS packets to initiate calls.
Apply
Click Apply to save your changes back to the Prestige.
