Type the login name assigned by your ISP for this remote node.
Select this check box if your ISP assigned you a fixed IP address, then enter the
IP address in the following field.
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.
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).
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).
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.
Select this check box to turn on RIP (Routing Information Protocol), which allows
a router to exchange routing information with other routers.
