Note New port values that may be specified for these LAN servers are restricted. The new port value

To specify server port numbers:
1. From the main menu, click Setup, and
then click Server Ports.
2. Enter the port number next to the server
type.
3. Click Apply.
The window refreshes to display the new
port numbers.
Dynamic DNS
Dynamic DNS allows you to dynamically update a pre assigned domain name with the Internet IP address
learned by the DSL modem. The SpeedStream router supports client updates to DynDNS.org
(http://www.dyndns.org). To use the Dynamic DNS service, you must first set up a free account at
www.dyndns.org. When the account is successfully established, you will be provided a username and
password for your account. You must also register any DNS host names you wish to use with the
DynDNS.org service. The client supports the updating of two host names. When configured correctly, the
DSL modem will automatically determine your Internet IP address and update the DNS server at
DynDNS.org. After the update, you can use your host name to access services, such as a web or mail
server, by name instead of using the IP Address. All operation and errors are stored in the modem's
System Log.
Note Access from the WAN to the LAN might be restricted by NAT/NAPT or the firewall. These
services need to be configured before attempting to access servers on your LAN side.
