3.8.4 Dynamic DNS

You can assign a fixed host and domain name to a dynamic Internet IP address.
Each time the router boots up, it will re-register its domain-name-to-IP-address mapping with the
DDNS service provider. This is how Internet users can access the router through a domain name
instead of its IP address.
Note: make sure that you have registered with a DDNS service provider before enabling
this feature.

3.8.5 Special Application

This is a feature for users to open "holes" on the router's built-in firewall triggered by outgoing
packets. Some NAT unfriendly applications require users to do so for normal operation. For
example, QuickTime requires users to add a special application rule to turn on WAN port 6970 to
6999 when an outbound packet using source TCP port 554 is received.
