LABEL DESCRIPTION 
Get IP Address 
Automatically from 
Remote Server 
Type the login name assigned by your ISP for this remote node. 
Used Fixed IP 
Address 
Select this check box if your ISP assigned you a fixed IP address, then enter the 
IP address in the following field. 
My WAN IP Address  Leave the field set to 0.0.0.0 (default) to have the ISP or other remote router 
dynamically (automatically) assign your WAN IP address if you do not know it. 
Type your WAN IP address here if you know it (static). This is the address 
assigned to your local ZyWALL, not the remote router. 
Remote Node IP 
Address 
Leave this field set to 0.0.0.0 (default) to have the ISP or other remote router 
dynamically (automatically) send its IP address if you do not know it. Type the 
remote gateway's IP address here if you know it (static). 
Remote IP Subnet 
Mask 
Leave this field set to 0.0.0.0 (default) to have the ISP or other remote router 
dynamically send its subnet mask if you do not know it. Type the remote 
gateway's subnet mask here if you know it (static). 
Enable SUA  Network Address Translation (NAT) allows the translation of an Internet protocol 
address used within one network to a different IP address known within another 
network.  
SUA (Single User Account) is a subset of NAT that supports two types of 
mapping: Many-to-One and Server. When you select this option the ZyWALL will 
use Address Mapping Set 255 in the SMT (see the section on menu 15.1 for 
more information). 
Select the check box to enable SUA. Clear the check box to disable SUA so the 
ZyWALL does not perform any NAT mapping for the dial backup connection. 
Enable RIP  Select this check box to turn on RIP (Routing Information Protocol), which allows 
a router to exchange routing information with other routers.
