The following table describes the labels in this screen.
7.5  The LAN Port Roles Screen 
Use the Port Roles screen to set ports as part of the LAN, DMZ and/or WLAN interface. 
Ports 1~4 on the ZyWALL 5 and ZyWALL 35 ports can be part of the LAN, DMZ or WLAN 
interface. The ZyWALL 70 has a separate (dedicated) LAN port, so ports 1~4 can be set as 
part of the DMZ and/or WLAN interface.
"
Do the following if you are configuring from a computer connected to a LAN, 
DMZ or WLAN port and changing the port's role:
A port's IP address varies as its role changes, make sure your computer's IP address is in 
the same subnet as the ZyWALL's LAN, DMZ or WLAN IP address.
Use the appropriate LAN, DMZ or WLAN IP address to access the ZyWALL.
To change your ZyWALL’s port role settings, click NETWORK > LAN > Port Roles. The 
screen appears as shown.

DESCRIPTION
Enable IP Alias 1, 
2
Select the check box to configure another LAN network for the ZyWALL.
IP Address
Enter the IP address of your ZyWALL in dotted decimal notation. 
Alternatively, click the right mouse button to copy and/or paste the IP address.
IP Subnet Mask
Your ZyWALL will automatically calculate the subnet mask based on the IP 
address that you assign. Unless you are implementing subnetting, use the subnet 
mask computed by the ZyWALL.
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.
