LABEL
Private This parameter determines if the ZyWALL will include the route to this remote node in
its RIP broadcasts. If set to Yes, this route is kept private and not included in RIP
broadcast. If No, the route to this remote node will be propagated to other hosts through
RIP broadcasts.
RIP Direction 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.
RIP Version 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.
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 or PPTP, NetBIOS packets cause unwanted calls.
Allow from WAN to Select this option to forward NetBIOS packets from the WAN port to the LAN port.
