Check Phase 1 Proposal Settings

AWS Knowledge Center Videos: “How do I check my VPN tunnel status in AWS?”

Ensure that both sides have at least one Phase 1 proposal in common. Otherwise they will not connect. If there are many proposals in the list, this will slow down the negotiating of Phase 1. If its too slow, the connection may timeout before completing. If this happens, try removing some of the unused proposals.

NPU offloading is supported when the local gateway is a loopback interface.

Check For Ip Address Leaks

Your IP address is like your address online. Its a lot more personally identifiable than a DNS address. A VPN masks your outgoing information source and the data thats transferred along from website to website. Thats why its recommended to hide your IP with a VPN.

Your real IP versus the IP your VPN provider gives you should always be different. If not, your IP is leaking. You can run this test on any device that has a VPN installed.

Heres how:

Step 1)Check your real IP address

Step 2) Turn on your VPN and choose any country server

Step 3) Check your IP address again by refreshing the page

Step 4) Thats it youre protected. As you can see, the IP address is different, indicating that the VPN is working correctly.

Make sure to check that the country server you connect to always matches the country displayed in the IP address checker. If not, your IP may be leaking.

Ways To Check If Your VPN Is Working Properly

When your VPN is on, there are several methods you can use to find out if its working checking if your Surfshark VPN works is a piece of cake. Just look for icons on your dock, toolbar, menu bar, etc.

  • If the icon is grey, then your VPN is off
  • If it turns green or blue, its on

Or, you can check your VPNs status by going to Settings > VPN on any device. However, if you need more than visuals to know that your VPN is working, follow any of these methods below:

  • Check for DNS leaks
  • Check for IP address leaks
  • Check for WebRTC leaks
  • Check if you can access geo-blocked content
  • All tests are equally important as they show accurate information about your VPN. You can choose to perform just one test or all of them .

    How To Examine Ip Leaks In My VPN

    VPNs also serve an important function of masking your IP address in addition to encrypting your data. This enables using public addresses as affixed by VPN servers. However, you might be subjected to a number of VPN privacy leaks. These will result in your actual IP address being exposed along with your browsing history. The most common types of leaks are:

    IPv6 Leaks

    This happens when your VPN does not support IPv6 addresses and must route the data without encryption. Thus, your actual location will be exposed via the IP address in use. There are 2 ways of fixing this issue:

  • Select an IPv6 Supported VPN.
  • Alternatively, you can deselect IPv6 routing through your existing VPN service.
  • DNS Leaks

    Domain Name Systems are used by devices to send requests for translations into numerical IP addresses. You can say it acts like a telephonic directory. However, your ISP might attempt to intercept your DNS request and reroute them to their channels before sending it to you.

    Naturally, this will show your browsing activities to them. However, a VPN can stop this. Nevertheless, if not configured correctly, your VPN can allow this to happen. The best way to avoid it is to take up a VPN which offers DNS leak protection.

    WebRTC/STUN leaks

    The best way to test your VPN would be to go to ipleak.net. However, if you want to get rid of the problem altogether, simply turn WebRTC off.

    Difficulty Establishing A Tunnel

    How to Find My Router IP Address Using CMD

    If everything seems to be working well, but you can’t seem to establish a tunnel between the client and the server, there are two main possibilities of what could be causing the problem. The first possibility is that one or more of the routers involved is performing IP packet filtering. IP packet filtering could prevent IP tunnel traffic. I recommend checking the client, the server, and any machines in between for IP packet filters. You can do this by clicking the Advanced button on each machine’s TCP/IP Properties sheet, selecting the Options tab from the Advanced TCP/IP Settings Properties sheet, selecting TCP/IP Filtering, and clicking the Properties button.

    The other possibility is that a proxy server is standing between the client and the VPN server. A proxy server performs NAT translation on all traffic flowing between the client and the Internet. This means that packets appear to be coming from the proxy server rather than from the client itself. In some cases, this interaction could prevent a tunnel from being established, especially if the VPN server is expecting the client to have a specific IP address. You must also keep in mind that a lot of older or low-end proxy servers don’t support the L2TP, IPSec, or PPTP protocols that are often used for VPN connections.

    Check VPN Connection Status From The Command Line

    If you want to know if any VPN-connection is active then the following invocation is useful:

    nmcli con | grep -i vpn

    Depending of the connection status you will get either

    VPN099     ...  vpn              wlan0

    This will show just the active connections:

    nmcli con show --active

    And you can grep for vpn, if needed:

    nmcli con show --active | grep -i vpn
    • Limiting this to just the active connections is definitely a good plan. I’m not sure why you included the -i in the grep though. The output is probably not going to change case and you might match those letters in a wifi SSID.

    We can do this using nmcli command:

    nmcli con status id your-vpn-connection-name

    If your VPN connection is connected, you will see the connection information but if your VPN connection is disconnected, you will see something like this:

    Error: 'your-vpn-connection-name' is not an active connection.

    How To Use Glasswire To Check VPN Encryption

    How to check your VPN connection on Windows 7
  • Download, Install and Run Glasswire.
  • Activate your VPN.
  • Find your VPN listed there.
  • Verify its encryption status.
  • All the traffic coming to your device should be routed through the VPN using SSL/HTTPS. Nevertheless, a tiny chunk of data might not be. This is called a VPN handshake and the size will remain the same throughout.

    Just like Glasswire, Wireshark is one more VPN verification tool. In fact, it is more accurate than Glasswire as it checks individual data packets coming or going from your device. Thus, you will be able to see whether the data is encrypted or not.

    In order to do this, you must follow the same procedure as for Glasswire. Be sure to download the right version according to your Windows 32-bit or 64-bit.

    The Acceptance Of Unauthorized Connections

    Now that I’ve discussed reasons why a connection might be refused, let’s take a look at the opposite problem in which unauthorized connections are accepted. This problem is much less common than not getting connected at all, but is much more serious because of the potential security issues.

    If you look at a user’s properties sheet in the Active Directory Users And Computers console, you’ll notice that the Dial In tab contains an option to control access through the remote access policy. If this option is selected and the effective remote access policy is set to allow remote access, the user will be able to attach to the VPN. Although I have been unable to re-create the situation personally, I have heard rumors that a bug exists in Windows 2000 that causes the connection to be accepted even if the effective remote access policy is set to deny a user’s connection, and that it’s best to allow or deny connections directly through the Active Directory Users And Computers console.

    How To Test For Dns VPN Leaks

    Sometimes when you are using a VPN, a DNS leak can occur. This happens when your DNS queries are sent outside of the secure VPN encrypted tunnel and your data is sent through your default DNS servers rather than the secure, anonymous VPN server. Often, a DNS VPN leak is due to improper configuration of your network settings.

    Unlike testing for a webRTC leak, the best way to check for a DNS leak is to use a website. There are a number of free websites that you can use to test for a DNS leak, such as DNSleak.com*.

    If you find that youre dealing with a DNS leak, there are several fixes you can try. Visit DNSleaktest.com* to find the best solution for your situation.

    Connections To Clients With Dual Nics

    Sometimes a user’s endpoint utilizing the client VPN connection may have connection issues to LAN endpoints that have dual NICs. Often, LAN endpoints have both a WAN and a LAN NIC. If these devices are unpingable from an endpoint connected via client VPN, check the routes on the LAN endpoints. In Windows, open the command prompt and type the command “route print”. In macOS, open up the terminal and type the command “netstat -nr”. Check that there are gateways set for the LAN routes and not just the WAN.
