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?

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 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.

How to forward port on telkom mega 100wr router


You have two options:
1. You can open port using router's web interface. Check what ports used your software, what protocol TCP/UDP/BOTH then go to web interface's virtual server and add new user's rule. Then you have to save and reboot router. Every time your PC IP changed (static IP recommended) or program you using changed port number you have to do web interface operation again.
2. Download and install Router Commander (fully compatible with your router) and that's all. The software will forward ports automatically

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.

If this is a DSL Gateway Router, check the settings on the modem and make sure that the DHCP server is enabled.
it woould be of great help if you could provide the exact model number of the Netopia modem so that I could check if there is configuration page which you can access and check the settings..

Connection with Netopia Cayman 3347w is very slow and becoming unbearable


Explaining an opinion on DSL's speed doesnt help fix a problem. Not to mention the fact that DSL is on a digital subsciber line, your own phone number, not the neighbors, you have it backwards, its cable that can have its speed impaired if all your neighbors go on.

Anyway, I am an expert with netopias. I trouble shoot them all day long on people's DSL connections. The symtopms that MacWyb is describing sounds like he has degregation of service that needs to be fixed by maintenance. They can do whats called a rip and rebuild, where they take off the virtual circuit and virtual path (vp and vc) and then build it right back, this clears this type of problem up quite often. It would also be a loose wire at the D-mark, the gray box on the side of your house, thats happened to me twice now. Or, It could be you're on a redback that has too many customers assigned to it, maintenance, if this is the case, would have to move your circuit, assign it to antoher redback, or brass router, whatever they're on.

In anycase, It means a call in to technical support with your ISP. They will create a trouble ticket to look at it for you.

This is all taking for granted you dont have a buzz on your phone (which would make it a telco issue, a call to your local phone company to fix the line), and that you have all your DSL filters installed on every phone in the house, including fax machines, etc.

It didn't work for me.
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.
