SpeedStream Router User Guide

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

must be in the range 1024-59999. Port values below 1024 are reserved for well-known port values, and

values above 60000 are used for port forwarding.

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.
