Telent is usually not an option these modems but will depend on the service provider if this feature was set up. Plug in and connect a PC to the LAN side of the modem. Refresh the network connection on the PC you connected to get the IP address from the modem. Once this is completed, open a web browser up. In the address enter http://192.168.100.1 and this should take you to the modem's management page as this is what most DSL modems use. Make sure to have your old user name and password as most modems will prompt for this.

Where is the password located at


Hey, the Netopia routers do not have a default username and password. If a password is already set up, you might need to reset the router.

In order to log into the router you need to Telnet into it.
If you are using Windows XP, you can start Telnet from Start>Accessories>Communications>Telnet

if you are using Windows Vista or Windows 7, Telnet is not enabled by default. You need to enable it first. You can quickly re-enable Telnet by following these steps:

Start
Control Panel
Programs And Features
Turn Windows features on or off
Check Telnet Client
Hit OK

After that you can start Telnet via Command Prompt. (or the Start menu)

then once you get into the Telnet Console, type in:
192.168.1.1

and the router interface will open up and let you chanfge settings.

Need to allow a telnet session thru a speedstream 5660 modem/router having a public ip and allow it to connect to a private ip on the internal LAN. how do i accomplish this?


According to the user manual:
Page 16:

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.


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:

.

.

.

Advanced Setup

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.

http://www.netopia.com/support/hardware/technotes/NQG_025.html
Server List (Port Forwarding) NQG_025 With NAT enabled, the IP addresses of nodes on your LAN are private since they are hidden from the Internet. IP Servers let you pass specific types of network traffic through the Netopia router's NAT interfaces. Once configured, selected types of network traffic, such as FTP requests or HTTP (Web) connections, will be forwarded to a specific host or server behind the Netopia router. Please Note: From the LAN (Local Area Network), you will also be able to access the servers that are responding to requests from the internet, but only using the internal private IP address. Access via the public IP address is not supported from a local ethernet connection. If your ISP is routing you multiple public IP addresses, you can also configure the router to forward all ports in one public IP to a designated private IP address on your LAN via Easy PAT List entries. For those instructions, see Quick Guide NQG_024: IP Mapping (Address Forwarding).
Please Note: If your router is currently running Netopia Residential Firmware with a web "GUI" configuration menu, this technote is not applicable to you. Most 3300 Series Netopia Gateways can be upgraded to Enterprise level firmware. Click Here! to purchase the upgrade key.
Related documents: NQG_039 NAT and the Basic Firewall
Firmware References:
  • v8.2 R1 (and up) - 3300 Enterprise Series
  • v5.3.7 (and up) - 4000 Series
  • v4.8.2 (and up) - R-Series

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

  1. From the Main Menu of router console screens, go to Quick Menus, and select Network Address Translation.
  2. Select Show/Change Server List.
  3. Select Easy-Servers.
  4. From the Show/Change NAT Server List screen, select Add Server.
  5. Select Service and the service and port you want to allow. If your service and port are not available in the pull-down menu, select Other. Selecting Other will allow you to enter a specific service port or a range of ports since fields are provided for both a First Port Number and a Last Port Number. To allow a specific service port, the First Port Number and Last Port Number should be the same. Select Okay.
  6. Next, enter the Server Private IP Address, or the private IP address of the host/server you are forwarding the service to, and the Public IP Address you want to associate with the same host/server. This value can be left set to 0.0.0.0 if you are using the WAN IP as the Public IP address. Note: If your ISP is routing you multiple static IP addresses, other then the one used for Internet access, you may create more than one server for specific service as long as all servers have a different Public IP Address specified. For example, with two web servers on your LAN you would need to create two Server List entries for TCP 80 (www-http). Since each specific port (service) can only be mapped once using any given Public IP Address, a distinct public address must be used for each TCP 80 server list entry. It is not necessary for you to specify more than one Local WAN IP Address or Public IP Address in your router's configuration. As long as you are connecting to your ISP via a public IP address used for NAT, they are responsible for routing all other IP addresses via that connection.

Conclusion
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. If you wish to filter traffic for your static IP mappings, please see the following Netopia Technote:

Netopia NAT


I know that most Netopia's I've worked with have been able to port forward single or ranges of ports to numerous internals from numerous externals.

Address Translation needs to be on.
IP Passthrough has to be off.
Then in NAT Easy Servers, setup port forwards and specify the external IP, internal IP, and ports (can forward all).

HOW TO DO THE PORTFORWARD


Some times you will need to open the Logical Ports on the router.
These are the logical ports.
For this you will need to open the set up interface of the router.
Once you open the set up interface of the router, you will be able to find the settings on the router where you can open the ports for the particular program.

If you are opening the ports for a special device in your network, then you must know the IP address of that device.
For example, wireless camera, DVR, X-box, Play station ...
You can choose the option PORT FORWARDING for a special device application.
If you just want to open the ports for all the network, then you can choose PORT TRIGGERING



For example ,
You have a Linksys wireless router and you want to open the ports for the X-box.
You have opened the set up interface of the router. You will see Application and Gaming TAB at the top.
If you click on that tab you will find different Sub tabs.
Click on Port Triggering => Here you can open the port numbers for the network.
Click On Port forwarding if you want to open the ports for a special device in the network.
Click Save settings once you open the ports on the router.

Some of the recommended port numbers for different applications :

IMAP ==> 143 SMTP : 25
HTTPS ==> 443 HTTP : 80
DNS ==> 53 FTP : 21
SNMP ==> 161 TELNET : 23
XBOX ==> 53, 80-88, 3074
PS3 ==> 80, 443-447 ,5223, 3478-3479, 3658, 10070-10080.
WII ==> 28910, 29900, 29901, 29920, 80, 443
VPN ==> 1723, 500, 443-447, 10000-20000

Can't Access Netopia Admin Panel Via IE


Try this and see if it works for you. Telnet into the modem. Hyperterminal will work fine for this.
Type config, then hit the enter key.
Type set, then hit the enter key.
At this point look at your monitor. Does the bottom line look like this?:
autoConfig (on) [ off | on ]:
If so, type off. Then hold the enter key down for several seconds untill you get to lines that look like this:
Netopia-3000/xxxxxxxx (top)>>
Then type save and hit the enter key.
When the screen says that the configuration data has been saved, type exit and hit the enter key. Then type restart and hit the enter key. When the modem restarts close hyperterminal and access the Netopia using your web browser.

Run NAT on your router
then lets say your LAN (router) 192.168.10.1
and your pc (webrouter) 192.168.10.100
