ZyWALL 5/35/70 Series User’s Guide

562 Chapter 33 SMT Menu 1 - General Setup

The IP address updates when you reconfigure menu 1 or perform DHCP client renewal.

IP Address

Update Policy:

You can select Yes in either the Let DDNS Server Auto Detect field (recommended)

or the Use User-Defined field, but not both.

With the Let DDNS Server Auto Detect and Use User-Defined fields both set to No,

the DDNS server automatically updates the IP address of the host name(s) with the

ZyWALL’s WAN IP address.

DDNS does not work with a private IP address. When both fields are set to No, the

ZyWALL must have a public WAN IP address in order for DDNS to work.

Let DDNS

Server Auto

Detect

Only select this option when there are one or more NAT routers between the ZyWALL

and the DDNS server. Press [SPACE BAR] to select Yes and then press [ENTER] to

have the DDNS server automatically detect and use the IP address of the NAT router

that has a public IP address.

Note: The DDNS server may not be able to detect the proper IP

address if there is an HTTP proxy server between the ZyWALL

and the DDNS server.

Use User-

Defined

Press [SPACE BAR] to select Yes and then press [ENTER] to update the IP address

of the host name(s) to the IP address specified below.

Only select Yes if the ZyWALL uses or is behind a static public IP address.

Use WAN IP

Address

Enter the static public IP address if you select Yes in the Use User-Defined field.

When you have completed this menu, press [ENTER] at the prompt “Press ENTER to Confirm…” to

save your configuration, or press [ESC] at any time to cancel.
