RIP & Multicast 

Setup

RIP Direction

RIP (Routing Information Protocol, RFC 1058 and RFC 1389) allows a router to 

exchange routing information with other routers. The RIP Direction field controls 

the sending and receiving of RIP packets. Select the RIP direction from Both/In 

Only/Out Only/None. When set to Both or Out Only, the ZyXEL Device will 

broadcast its routing table periodically. When set to Both or In Only, it will 

incorporate the RIP information that it receives; when set to None, it will not send 

any RIP packets and will ignore any RIP packets received.

RIP Version

This field is enabled if RIP Direction is not None. 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). 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.

Multicast

IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to 

establish membership in a multicast group. The ZyXEL Device supports both IGMP 

version 1 (IGMP-v1) and IGMP-v2. Select None to disable it.

Networking 

(NetBIOS over 

TCP/IP)

NetBIOS (Network Basic Input/Output System) are TCP or UDP 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. 

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. If your firewall is enabled with the default policy set to 

block WAN to LAN traffic, you also need to enable the default WAN to LAN firewall 

rule that forwards NetBIOS traffic.
Clear this check box to block all NetBIOS packets going from the LAN to the WAN 

and from the WAN to the LAN.
