VPNs (especially Nord and PIA) have ended up being so much popular among private networks mainly because they can link these networks across the internet without giving them the stress of spending extra cash on dedicated lines. Among these VPNs are Nord and PIA, which are highly reliable too.

What’s the issue?

There are two kinds of issues that tend to accompany VPN connections. These consist of:

  • The VPN connection being declined
  • The authorization of an unapproved connection

1.The VPN connection being declined.

Having a VPN client’s connection turned down is possibly the most common VPN issue these days. If your VPN server is declining client connections, the very first thing you need to do is to make sure the Routing And Remote Access to service are running.

Examine the authentication procedure

As soon as you have set up that there is a legitimate TCP/IP connection between the VPN client and server, which name resolution is working properly, the next thing to inspect is the authentication procedure.

You can also see which authentication techniques the VPN server is set up to use by going into the MMC command at the Run command. Now, choose the Add/Remove of Snap-In command from the Console menu. Select Routing And Remote access to from the list and click the Include button, followed by the Close and OKAY buttons.

2.The authorization of an unapproved connection

Now that I have gone over reasons that a connection may be declined let’s have a look at the opposite issue in which unapproved connections are authorized. This issue is much less common than not getting linked at all but is far more severe because of the prospective security problems.

If you take a look at a user’s properties sheet in the Active Directory Users And Computers console, you’ll observe that the Dial-In tab includes a choice to manage access to through the remote access to the policy. The user will be able to connect to the VPN if this choice is picked, and the efficient remote access to policy is set to allow remote access to. I have  been not able to re-create the scenario personally, I have heard reports that a bug exists in Windows 2000 that commands the connection to be accepted even if the efficient remote  access to policy is set to reject a user’s connection and that it’s best to allow or deny connections straight through the Active Directory Site Users And Computers console.

Both Nord and Private Internet Access VPN has these two issues, most commonly inquired. You can fix more of these issues, checking the comparison of both VPN company here.

Pro Tip: More things to examine

If the authentication techniques appear to be set properly, the next action is to inspect the method by which the client is trying to link to the VPN server. This would also be a great time to validate that the user really understands how to develop the VPN connection and that the user is using the proper username and password.
