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 or PPTP, NetBIOS packets cause unwanted calls.

Vantage can communicate with the device using Dial Backup if the main WAN connection
goes down.

DESCRIPTION
RIP (Routing Information Protocol) allows a router to exchange routing
information with other routers. The RIP Direction field controls the sending and
receiving of RIP packets.
Choose Both, None, In Only or Out Only.
When set to Both or Out Only, the ZyXEL device will broadcast its routing table
periodically.
When set to Both or In Only, the ZyXEL device will incorporate RIP information
that it receives.
When set to None, the ZyXEL device will not send any RIP packets and will
ignore any RIP packets received.
By default, RIP Direction is set to Both.
The RIP Version field controls the format and the broadcasting method of the
RIP packets that the ZyXEL device sends (it recognizes both formats when
receiving).
Choose RIP-1, RIP-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.
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 inter operability
between IGMP version 2 and version 1, please see sections 4 and 5 of RFC
2236.
Select this option to forward NetBIOS packets from the WAN port to the LAN
port.
Select this option to allow NetBIOS packets to initiate calls.
