FIELD
DESCRIPTION
IP Address
Assignment
If your ISP did not assign you a fixed IP address, press [SPACE BAR] and then
[ENTER] to select Dynamic, otherwise select Static and enter the IP address and
subnet mask in the following fields.
Rem IP
Address
Enter the (fixed) IP address assigned to you by your ISP (static IP address assignment
is selected in the previous field).
Rem Subnet
Mask
Enter the subnet mask associated with your static IP.
My WAN
Addr
Leave the field set to 0.0.0.0 to have the ISP or other remote router dynamically
(automatically) assign your WAN IP address if you do not know it. Enter your WAN IP
address here if you know it (static).
This is the address assigned to your local ZyWALL, not the remote router.
Network
Address
Translation
Network Address Translation (NAT) allows the translation of an Internet protocol
address used within one network (for example a private IP address used in a local
network) to a different IP address known within another network (for example a public
IP address used on the Internet).
Press [SPACE BAR] and then [ENTER] to select either None or SUA Only.
Choose None to disable NAT.
Choose SUA Only if you have a single public IP address. SUA (Single User Account) is
a subset of NAT that supports two types of mapping: Many-to-One and Server.
See
for a full discussion on this feature.
Metric
Enter a number from 1 to 15 to set this route’s priority among the ZyWALL’s routes. The
smaller the number, the higher priority the route has.
