2. Add the Dynamic DNS service and the login credentials.

set service dns dynamic interface eth0 service <dyndnsservice> host-name <host>
set service dns dynamic interface eth0 service <dyndnsservice> login <username>
set service dns dynamic interface eth0 service <dyndnsservice> password <password>

3.  Configure the location of the Dynamic DNS server.

set service dns dynamic interface eth0 service <dyndnsservice> server <server>
NOTE: This step is required when using afraid.org.
