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.
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-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, RIP direction is set to Both and the Version set
to RIP-1.
