HTTP Web-browser Access
Most HTML browsers can be used, though Internet Explorer 4.0 or Netscape 4.0 are recommended. IE 2.0 and Netscape 2.0 and their predecessors are not supported. The HTML interface can be used to access the LAN (or WAN) IP address or it can be used with FTP to upload and download files to and from the router.
To log on to the modem via HTML:
1 Bring up your favorite web browser.
2 Enter the Ethernet IP address of the router (10.0.0.1 or Speedstream) in the "Location" or "Address" area where you enter web page addresses.
3 Refer to "HTML Web Interface" on page 20.
HTML Web Interface
The HTML interface for the router first displays a page showing the current configuration of the router. The first page also provides links to the following functions:
Leads to a more detailed interface with several links that allow more in-depth configuration of functions available on the router. This interface provides the following links:
• Configuration Procedures
• Status and Statistics
• Command List
This is where the user manual ends. I would suggest clicking "Configuration Procedures" and find the section for configuring Network Address Translation (NAT).
In that section (if it exists), you'll want to provide the private IP address of the computer running the Telnet server and forward port 23 to this IP address.
If NAT capabilities do not exist, I would consider changing the router to Gateway mode (described in the user manual) and buying your own router to handle the NAT firewall.

Before You Start
Telnet into the Netopia router's Main Menu at 192.168.1.1 (if using the default IP setting). If your network has a different IP addressing scheme, modify this accordingly. Click Here! for instructions on using telnet and Hyperterminal (serial connection).
Login with the user name and password. The Superuser login is required to save changes. If you are unsure of this, contact your network administrator.
Don't forget to press the Enter key to save any entries. Hitting the back space, delete or tab without first hitting enter will undo any changes.
The Esc key will take you back towards the main menu screen.
Once you have completed your configuration, you should reboot the Netopia to save and apply your changes.

Server List Configuration
You have now configured your router for TCP/UDP port forwarding. If you have a switched connection (ISDN or Analog), you will need to either disconnect and reconnect your Internet connection, or restart your router for the Nat Server List changes to take effect.
