UPnP:
Select this checkbox to activate UPnP. Be aware that anyone could use a UPnP
application to open the web configurator's login screen without entering the router 's IP
address
Auto-configured:
Select this check box to allow UPnP-enabled applications to
automatically configure the router so that they can communicate through the router, for
example by using NAT traversal, UPnP applications automatically reserve a NAT
forwarding port in order to communicate with another UPnP enabled device; this
eliminates the need to manually configure port forwarding for the UPnP enabled
application.
4.4.5 DDNS
The Dynamic DNS function allows you to alias a dynamic IP address to a static hostname,
allowing users whose ISP does not assign them a static IP address to use a domain name.
This is especially useful for hosting servers via your ADSL connection, so that anyone
wishing to connect to you may use your domain name, rather than having to use your
dynamic IP address, which changes from time to time. This dynamic IP address is the
WAN IP address of the router, which is assigned to you by your ISP.
You will first need to register and establish an account with the Dynamic DNS provider
using their website (for example http://www.dyndns.org/).
