address.
Select Let DDNS Server Auto Detect only when there are one or more NAT
routers between the ZyWALL and the DDNS server. This feature has the DDNS
server automatically detect and use the IP address of the NAT router that has a
public IP address.

address if there is an HTTP proxy server between the
ZyWALL and the DDNS server.
