Edit Update IP Address:

You can select Yes in either the Use Server Detected IP field (recommended) or the User Specified IP Address field, but not both.

With the Use Server Detected IP and User Specified IP Address 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.
