Question about Netopia (3347NWG-ENT) Router (3347NWGENT)

1 Answer

VPN connection - Client cannot connect

The client receives the following error: VPN server may be unreachable or security parameters may not be configured properly for this connection. I'm using a netopia router 3347. I tried to follow directions to open up the necessary ports on the router but still the client is getting the same message. I set up the username on the server computer and provided the client with the username and password. I'm a novice at this...what else can I do? The firewall on the server is turned off right now.

    Please describe the configuration further. What device is the VPN server, and what device is the VPN client?

    What protocol is your VPN operating on (PPTP, IPSec, SSL?)

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.

Frequent VPN connection drop on my wifi


If you can't connect via the Internet to your workplace network from home (or another location), check the items in this list:

  • Make sure that you typed the virtual private network (VPN) server name exactly as provided by your network administrator.

  • You must have an active Internet connection for a VPN connection to work.

  • If your modem is external, make sure that the modem power is turned on.

  • Contact your network administrator to make sure that you have the appropriate connection and domain permissions on the remote access server.

  • This could be a certificate problem. For assistance, contact your network administrator.

  • A VPN connection won't work with an active Winsock proxy client. Contact your network administrator to make sure the Winsock proxy client is not enabled.

  • If you know the IP address (for example: 131.107.10.25) of a website, type that address in the address bar of your web browser and press Enter. If this works, there is probably a Domain Name System (DNS) resolution problem. For assistance, contact your network administrator.

  • If you have special software that's required or installed by your workplace, it could be part of the problem. For assistance, contact your network administrator.

  • If you know the IP address (for example: 131.107.10.25) of your VPN server, type that address for the VPN connection, and then press Enter. If this works, there is probably a DNS resolution problem. For assistance, contact your network administrator.

  • There could be a problem with the server you're trying to connect to. For assistance, contact your network administrator.

If you try to connect with a VPN connection and you see a message that says "The local computer does not support encryption" and has the error code 741, it's possible that the encryption that your computer uses doesn't match the encryption used by the VPN server. To change the encryption settings so that your computer uses the recommended setting of 3DES, follow these steps:

  1. Open Connect to a Network by clicking the network icon (eff2d36c-9e0d-4d1a-9859-3af14fa4ccfc_73.jpg or da12251d-1e9a-4032-afae-009876c6c5a3_80.jpg) in the notification area.

  2. Right-click the VPN connection, and then click Properties.

  3. Click the Security tab.

  4. Under Data encryption, select Maximum strength encryption (disconnect if server declines), and then click OK.

  5. Open Connect to a Network by clicking the network icon (eff2d36c-9e0d-4d1a-9859-3af14fa4ccfc_73.jpg or da12251d-1e9a-4032-afae-009876c6c5a3_80.jpg) in the notification area.

  6. Click the VPN connection, and then click Connect to try connecting again.

VPN in Microsoft Server 2003


The full form of VPN is Virtual Private Network. VPN gives extremely secure connections between private networks linked through the Internet. It allows remote computers to act as though they were on the same secure, local network. Allows you to be at home and access your company's computers in the same way as if you were sitting at work.

Almost impossible for someone to tap or interfere with data in the VPN tunnel. If you have VPN client software on a laptop, you can connect to your company from anywhere in the world. VPN goes between a computer and a network (client-to-server), or a LAN and a network using two routers (server-to-server). Each end of the connection is a VPN "endpoint", the connection between them is a "VPN tunnel".

When one end is a client, it means that computer is running VPN client software. You can use a virtual private network (VPN) to connect components to one network by using another network. VPN do this by "tunneling" through the Internet or another public network. With a VPN, connections across the public network can transfer data by using the routing infrastructure of the Internet, but to the user, the data seems to travel over a dedicated private link.

A VPN gives you the benefit of a dial-up connection to a dial-up server, plus the flexibility of an Internet connection. Using an Internet connection you can connect to resources all over the world. If you have a high-speed Internet connection at your computer and at your office, you can communicate with your office at full Internet speed. This is much faster than any dial-up connection that uses an analog modem.

VPNs use authenticated links to make sure that only authorized users can connect to your network, and they use encryption to make sure that others cannot intercept and cannot use data over the Internet. A Tunneling Protocol is a technology that helps make the transfer of information over the Internet more secure from one computer to another.

VPN technology also permits a corporation to connect to its branch offices or to other companies over a public network, such as the Internet, while helping to maintain secure communications. The VPN connection across the Internet logically operates as a dedicated wide area network (WAN) link.

VPN in Windows 2003 Server: You need a high speed Internet connection to configure and run VPN server. Two individual lan card must be present in a single system where you want to configure a VPN Server. The lan cards should ping each other. Also need a User which's Dial in allow access should be enable. Microsoft 2003 server two tunnelling protocols for a secure VPN connection, one is PPTP (Point-to-Point Tunnelling Protocol) which Provides data encryption using Microsoft Point-to-Point Encryption. The other is L2TP (Layer Two Tunnelling Protocol) which Provides data encryption, authentication, and integrity using IPSec.

Steps to create VPN Server in 2003 Server: At first I go to Start and point to Administrative Tools, then click Routing and Remote Access. Then I click the server icon that matches the local server name in the left panel of the console. If the Routing and Remote Access service was previously turn on, you may want to reconfigure the server.

To reconfigure the server Right-click the server object, and then click Disable Routing and Remote Access. Click yes to continue when you are prompted with an informational message. Then Right-click the server icon and then click configure and Enable Routing and Remote Access to start the Routing and Remote Access Server Setup Wizard. After that click Remote access (dial-up or VPN) to turn on remote computers to dial in or connect to this network through the Internet. Then I have Click to select VPN. In the VPN Connection window I click the network interface (Lan) which is connected to the Internet and go the IP Address Assignment window, then I click Automatically because there was present a DHCP server in network. However, if DHCP is not available, you must specify a range of static addresses.

If you use from a specified range of addresses, open the Address Range Assignment dialog box and Type the first IP address in the range of addresses that you want to use in the Start IP address box. Type the last IP address in the range in the End IP address box. Windows calculates the number of addresses automatically. After that I have accept the default setting of No, use Routing and Remote Access to authenticate connection request and finally Click Finish to turn on the Routing and Remote Access service and to configure the server as a Remote Access server.
For the remote access server to forward traffic properly inside your network, you must configure it as a router with either static routes or routing protocols, so that all of the locations in the intranet are reachable from the remote access server. It also need for security purpose.<SPAN style="LINE-HEIGHT: 115%; FONT-FAMILY: 'Verdana','sans-serif

I have an older Cisco PIX 506 with two VPN connections. One links two offices (PIX-PIX VPN) together, another is for staff to access email & files. The file server on the local LAN the PIX is on are...


It could be a missing route... are the file server and email server on the same subnet? If they are then it is possibly not a routing issue.

Also it would be worth checking the tunneling settings for the VPNs... if you have specifed either only the fileserver subnet or specifically the file server address, then this could be the reason they can get to nothing else.

Hope that this has helped a little :)

This is an excerpt from a MS Technet page for error 53:
Resolutions: 1) if it is domain environment, check your WINS; 2) if it is peer-to-peer workgroup, enable NetBIOS over TCP/IP; 3) make sure the machine is running; 4) make sure file and Printer Share enabled on remote computer; 5) make sure client for ms networks is enabled on local computer; 6) make sure you type the correct name. 7) Make sure no firewall running or any security setting.
Pay close attention to #s 4 and 5 - I suspect XP pro might not be open enough.

Vpn error. 800


Resolutions: 1) if you have firewall, open TCP Port 1723, IP Protocol 47 (GRE). 2) make sure you can reach the VPN server by using ping. Sometimes, poor connection can cause this issue too. 3) You may need to updated firmware on a router or firewall if other OS (win9x/nt/me/w2k) works except XP. 4) The VPN server may not be able to get IP from DHCP for the VPN client. So, you may want to re-configure VPN host networking settings. For XP pro VPN host, go to the Properties of the VPN>Network, check Specify TCP/IP address and Allow calling computer to specify its own IP address, and uncheck Assign TCP/IP addresses automatically using DHCP. 5) Make sure no other secure software blocks your access, for example, if you use Norton secure software, you may need to add the remote client's IP so that the client can access. 6) If your VPN running on a Windows RRAS with NAT enabled, you may want to check the NAT settings. 7) If you can establish the VPN from the desktop at home but not from the laptop. Make sure no security software like Microsoft OneCare software that blocks the GRE.
