Configuring an .opvn file to allow certain fully qualified domain names down the tunnel
If you are using an .opvn file to connect to a VPN server, you may want to configure it to allow certain fully qualified domain names (FQDNs) to pass through the tunnel. This can be useful if you only want specific websites or services to be accessed through the VPN while allowing others to bypass it.
In this article, we will guide you through the process of configuring an .opvn file to allow certain FQDNs down the tunnel. Please note that this guide assumes you have basic knowledge of VPNs and are comfortable editing configuration files.
Step 1: Open the .opvn file
First, locate the .opvn file you are using to connect to the VPN server. This file contains the configuration settings for your VPN connection. Open the file using a text editor of your choice.
Step 2: Add the necessary configuration lines
Within the .opvn file, you will find various configuration lines. To allow certain FQDNs down the tunnel, you need to add the following lines:
route-nopull
route <FQDN1> <VPN_SUBNET_MASK>
route <FQDN2> <VPN_SUBNET_MASK>
Replace <FQDN1> and <FQDN2> with the fully qualified domain names you want to allow through the VPN. Make sure to include the VPN subnet mask, which typically is 255.255.255.255.
Step 3: Save and close the .opvn file
After adding the necessary configuration lines, save the .opvn file and close the text editor.
Step 4: Restart your VPN connection
To apply the changes to your VPN connection, you need to restart it. Disconnect from the VPN server and then reconnect using the updated .opvn file.
Once connected, only the specified FQDNs will be routed through the VPN tunnel, while all other traffic will bypass it.
It is important to note that if you want to allow multiple FQDNs, you can add additional "route" lines following the same format as above.
Additionally, if you want to allow all traffic through the VPN except for certain FQDNs, you can use the "route-nopull" line to exclude the default route from being pulled.
By configuring your .opvn file in this way, you can have more control over which FQDNs are routed through the VPN tunnel.
Configuring an .opvn file to allow certain fully qualified domain names down the tunnel can be a useful way to control which websites or services are accessed through your VPN connection. By following the steps outlined in this article, you can easily add the necessary configuration lines to your .opvn file and specify the FQDNs you want to allow through the VPN.
Remember to save and restart your VPN connection after making the changes. If you encounter any issues, double-check the syntax and ensure that the FQDNs and VPN subnet mask are correct.
