DESCRIPTION

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 ZyWALL 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

The RIP Version field controls the format and the broadcasting method of the RIP

 

packets that the ZyWALL 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-2Band RIP-2Msends the routing data in RIP-2 format; the difference being

 

that RIP-2Buses subnet broadcasting while RIP-2Muses 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, RIP direction is set to Both and the Version set

 

to RIP-1.

10.5 WLAN Port Roles

Use the Port Roles screen to set ports as part of the LAN, DMZ and/or WLAN interface. Ports 1~4 on the ZyWALL can be part of the LAN, DMZ or WLAN interface.

Connect wireless LAN Access Points (APs) to WLAN interfaces to extend the ZyWALL’s wireless LAN coverage. The WLAN port role allows the ZyWALL’s firewall to treat traffic from connected APs as part of the ZyWALL’s WLAN. You can specify firewall rules for traffic going to or from the WLAN. The WLAN includes the ZyWALL’s own WLAN and the Ethernet ports in the WLAN port role.

The following figure shows the ZyWALL with a built-in wireless card and an AP connected to an Ethernet port in the WLAN port role.
