This article is for those who use OpenVPN on the server side. However, unlike IPsec, OpenVPN does not work by itself. It works through a client software package. The most common solution is OpenVPN GUI, which functions as a client. However, for more advanced OpenVPN configurations, you may want to use the command line. The OpenVPN server is mostly for people in small home offices that need to connect to the outside world and for people who want to run their own server. As you can see, each one of these blog posts is very different in terms of tone, audience, and subject matter. You cannot approach them in the same way. How to write the blog post You’ve chosen your
The OpenVPN tunnel is not forwarding any traffic. If you have configured everything correctly, the OpenVPN tunnel is not working because of a device or network misconfiguration. (Resolution: Check for DNS leaks.) When you are first learning to use OpenVPN you may have assumed that once you configured everything correctly and had it up and running that you were done. But there’s a long list of things that can go wrong after that, including OpenVPN being unable to reach the Internet.
- Some users claim that OpenVPN does not forward traffic, which can cause various problems when you urgently need this software.
- If you are sending signals to devices on the local network, you may not be able to do so using a remote client with OpenVPN.
- As a temporary solution, you can add an exception to the firewall and then change the system settings.
- Whitelisting OpenVPN in your antivirus or resetting the TAP adapter may also help, but if all else fails, try other specialized software.
OpenVPN is a free, open-source application that can be used to establish and deploy virtual private networks and other secure point-to-point or site-to-site connections.
Although OpenVPN is known as one of the most popular VPN protocols and is known for its security and connection speed, OpenVPN may not forward traffic or may even stop working.
You can always check out VPN software without port forwarding, but if this feature is essential to you, you should look into this further.
If you experience this problem, check the following solutions.
What should I do if OpenVPN does not forward traffic?
1. Add a firewall exception
- Click the Start icon in the taskbar, type Firewall and open Firewall and Network Security.
- Click Allow an application through the firewall.
- Click Change settings (with administrator rights).
- Find OpenVPN in this list and click on the Private and Public checkboxes.
- If it is not in this list, press the Allow another application to browse and select it.
2. OpenVPN whitelist in your antivirus
The exact steps to perform this action depend very much on the antivirus software you are using, but you can usually configure this setting by opening the Settings menu.
As for the firewall: If your antivirus software denies OpenVPN access to the network, it will cause the problem we are talking about in this article.
3. TAP adapter reset
- Right-click on the Start button and select Device Manager.
- Expand the Network Adapter menu.
- Find all TAP drivers, right click and select Uninstall Device.
- Open the Actions menu and select Scan for Device Changes.
4. Checking that DHCP service is working
- Click the Start icon in the taskbar, type services, and then click it.
- Right-click on the DHCP client and select Properties.
- Set the start type to Automatic.
- Press OK.
5. Ditto coils DNS
- Run the command line as administrator: Press Ctrl + R, type cmd, hold down Ctrl + Shift, and press Enter.
- Copy and paste the following lines (press Enter between each line):
- ipconfig /flushdns
- ipconfig /registerdns
- ipconfig /release
- ipconfig /renew
- NETSH winsock reset catalog
- NETSH int ipv4 reset reset.log
- NETSH int ipv6 reset reset.log
- Restart the computer to apply the new changes.
6. Switch to a secure VPN client
If OpenVPN does not forward traffic to your device, you need to install a reliable VPN application that supports the OpenVPN protocol.
Private Internet Access (PIA) is a good option because it automatically modifies the system firewall and installs custom TAP adapters.
PIA supports a number of VPN protocols, including OpenVPN, L2TP/IPsec, and PPTP, and allows full customization of OpenVPN connection settings.
More importantly, you can even choose your own cryptogram:
- AES-128 (GCM)
- AES-256 (GCM)
- AES-128 (CBC)
- AES-256 (CBC)
Other useful features:
- OpenVPN and WireGuard protocols
- Separate tunnelling and emergency switch
- Private DNS servers and DNS leakage protection
- 24×7 chat support
- 30 days money back guarantee
