when you select a specific interface in the
Primary Binding Address Interface
field.

- If the interface has a dynamic IP address, the DDNS server checks the source
IP address of the packets from the USG for the IP address to use for the domain name.
You may want to use this if there are one or more NAT routers between the USG and
the DDNS server.
Note: The USG may not determine the proper IP address if there is an HTTP proxy
server between the USG and the DDNS server.
Custom
- If you have a static IP address, you can select this to use it for the domain
name. The USG still sends the static IP address to the DDNS server.

as your (dynamic) domain name. This feature is useful if you want to be able to use,
for example,
www.yourhost.dyndns.org
and still reach your hostname.
