Question about Netopia ADSL 2+ MODEM 10/100 EN AND USB FIREWALL SECURITY Router (2241NVGX)

AT&T Netopia DSL modem not opening ports for web servers

We moved and at this new location we have AT&T as our Telco. They provided us a Netopia Modem/Router combo. They also provided us five static IPs.
No matter what we do, our webserver (we host our own webserver) cannot be accessed. We have internet access so the line is working but Netopia is not letting anyone see our webserver.

Any ideas?

Find wep key 3347nwg -006


Try Password: admin, 1234, serial number of unit (written underneath)

Or you could connect to it with a Ethernet Cable and open web browser and go to 192.168.1.1 or 192.168.1.0 or 192.168.1.254 and you can access settings from there and change WEP password.

Last resort, just use the reset button on the unit.

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:

I need to find a driver/sortware program to get my netopia 3D reach wireless adapter up and running. all i can find are these driver scans that want me to install them and scan my computer to tell me I...


Here's a driver-free, software-free solution.

Turn your cable-modem (or DSL-modem) off.
Turn your Netopia off.

Connect:

Ethernet--port on cable-modem <-- cable --> WAN port on Netopia.

One LAN port on Netopia <-- cable --> network-port on your computer.

Turn the cable-modem on, and wait until its lamps settle-down to a repeating pattern.

Turn the Netopia open, and wait until its lamps settle-down to a repeating pattern.

Restart your computer.

Click Start
Click Run
Type CMD
Press Enter
Type IPCONFIG
Press Enter
Look for output like: Default Gateway ... 192.168.123.456
Start Internet Explorer
Type http://192.168.123.456 (or whatever numbers you see)
Login to the web-server running "inside" the Netopia.
Click to run the "Wireless Networking Setup Wizard".
Enter an SSID of your choice.
Select the 'WPA' level of encryption.
Enter a network-password of your choice.
Click OK
Restart the router (if it did not automatically restart).

Disconnect the Ethernet cable from your computer's network-port.
Click "View Available Wireless Networks".
Click the SSID of your new network.
Click Connect.
Enter the password, when prompted.
Voila! You have a wireless connection to the internet.

I need to get port forwarding info from a retired netopia 4541 adsl router. does it have a web interface or do I need to use telnet?


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.

Netopia 3347 moved to a different location/tel number


If you got the netopia in anyone of the 13 states that ATT controls, then that netopia will work in any other state, not just the phone number it was attached to. We are implementing technology now that it will be phone specific, but most people dont have that installed yet.

All you have to do is reset the netopia, open a browser, type 192.168.1.254 and set it up with the new username and password you created when you got your new DSL service.

Should the username be the email address from At&t that controls the DSL line, or should it be the username to get into the Netopia modem?

Netopia 2241 Modem losing sync?


If your modem is losing sync with ADSL 2 that means that your line has a problem. Try having your DSL provider move you to a new Cable and pair.
