Question about Netopia (3347NWG-VGX) Wireless Router (3347NWGVGX)

Netopia losses connection to internet and to server and vp phones

I am a small business using a file server with Windows Business Server 2003. My internet provider (AT&T) recently replaced my old Cayman router with a Netopia 3347-02. Since then we have had nothing but problems. My tech support people tried unsuccessfully to change the ip address of the Netopia router to the ip address of the old cayman router, but each time they tried, the router would freeze and would require a hard boot (back to the factory settings) to restart it. AT&T finally convinced my IT people that the ip address could not be changed in the router and so we changed the ip address in the server and most of my software. For the most part we are up and running, but when we plug in my Toshiba VP phones, the internet goes down within about 5 minutes and can only be restarted by unplugging the vp phones and doing a soft re-boot on the router. Toshiba says their VP phones do not require an ip address to be programmed into the phones, so apparently that is not the problem. Also, about twice a week all the desktop computers lose connection to the internet and/or the file server. If we lose connection to the internet and file server at the same time, we can do a soft reboot of the router and get restarted, but shortly thereafter, we lose connection to just the file server and have to reboot it. I have had 4 different tech people from 3 different companies try to diagnoise my problems and every one of them have told me that this Netopia router is not designed for a business setting. AT&T does not agree. Can you help me?

    Thank you for your help. My tech was very doubtful abou the DHCP conflict, but it turns out you were right. He resolved the DHCP conflict and now we can plug the phones in without it taking down the internet, however, the phones still do not operate and the display screen says "searching for IPU". They are Toshiba IP Enterprise phones - model IP2010-SD. Both our static IP address and the address of our router have changed since the phones last worked. Do you have any additional suggestions?

The Netopia Is a business-class router. Not clear from you question are you running Small Business Server or Windows Server 2003? If its the former, it has a wizard that will configure your LAN & the Netopia.
You can configure the Local IPs on the Netopia in the DHCP settings in expert mode.
The VP (VOIP?) phones are acting as a DHCP server & re-configure the network to their defaults.
Any 1/2 decent IT person (witth some real qualifications) could figure straiten this out...beware of "Techs"

You can change the IP of the router via the GI going in through expert mode and configeration. You can also telnet in, then enter the keyword "magic" then configure. You should get top>>. type "view" and you can step through all the setting, To change a setting step down through the tree by "keyword name"<CR>. until you get to correct keyword level, then to switch an option on/off "set on" or off or "set some-value", then save, then quit or top tio get back to top level of config tree. Known problem is that the target SNR for the down stream direction is set to zero [type in dmt ds tsnr to display this]. Looks like this modum is poorly implimented as it fails to down the speed if SNR drops below 6dB, I replaced it foe D-link DSL-3640B due to these performance problems. The 3640B gets hot but it keeps the SNR above 4 dB from 6500 kbps down to 4000kbps at night and back up next day. (dja.)

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:

hello, is your server 2003 setup as DNS server??? if so have you configured forwarder for non- local access? is that a home? or business? is it work do you not have a static public IP address.

here whats happening, when you manually give client the DNS they can resolve everything local fine but when a request for outside world is sent your server doesn't know what to do with it. log on to server open up your dns console, right click on your domain, then select properties, find forwarder tab and add a any reliable public DNS server there ( ie I use 4.2.2.1 (att)) server pretty quick and reliable.
so next time a request is sent to your server and server doesn't have that information it forward that to the public DNS and you will be good to go.

but from your setup i am gathering there is plently you do to improve your network and reduce your headache of manual work.

typical setup: 1- setup DNS with forwarder
2- Setup DHCP on Server instead of router ( trust me its easier than you think)
3- put all setting to for clients in DHCP options
4- reserve IPs for servers/prineters/switches etc.
5- set all clients for DHCP
6-disable DHCP on router.

let me know if your need help setting it up.

i hope this helps
good luck

Perhaps the server is setup with DHCP services enabled?

If it's a windows server, try going to control panel--administrative tools and look for DHCP server

If it's there open it, then right click the server's name and choose disable dhcp.

Then reboot the server and the desktop and see if that works.

also the server may have a static IP address that would need to be changed to dhcp

VPN connection - Client cannot connect


Hi mwells960

Theres alot of differnet things i could ask you, but im going to assume you're jsut setting up a basic VPN. That means that somebody is telecommuting to work and wants to hit the server at work.

That means you have a static ip at work, and your at home workers has whatever, a internet connection lets say. Im thinking DSL with ATT since its a netopia 3347N.

If the netopia has a gui interface, you cant vpn thru it. Its not a VPN router. Its a residential router that you're trying to make do too much.

The sad news is, you can't upgrade it to an Enterprise having firmware router anymore, netopia use to offer that, but when Motorolla bought them out last year, they did away with that nice little feature. For true VPN'ing with a router, first, go get a VPN router to start with.

Most people accomplish what you are doing by putting the netopia in to bridegemode, and then putting a VPN router like a linksys behind it.

My website on my network open the netopia router page


You need to somehow setup the internal DNS to route all requests for the specific domain name, to your internal website.

Or, setup the netopia to allow loopback connections.

If you have a 2003 Server OS, chances are that the server is handling DNS requests, at least internally.

This tutorial has a good example of how to create domains internally:
http://www.simongibson.com/intranet/dns2003/

Just a couple of tidbits when using this approach:
You will essentially be controlling the DNS for the domain internally anyways. Meaning, any subdomains, mail exchangers etc., for the domain will have to be configured as well.

Good Luck.

Netopia DSL Router (DHCP Server) was giving address to connect to Internet


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..

Netopia Router - No Connection, Clicking


Yes, you need to swap the router out.

This is assuming you dont have the netopia in bridge mode with another device behind it.
