How to Implement Virtual Private Network (VPN) Split Tunneling on Your Dedicated Server

Implementing Virtual Private Network (VPN) split tunneling on a dedicated server involves configuring the VPN server software to allow some traffic to bypass the VPN tunnel while directing other traffic through it. This is useful when you want to access both local and external resources simultaneously.

Here are the steps to implement VPN split tunneling on your dedicated server:

1. Choose a VPN Server Software:

• There are various VPN server software options available, such as OpenVPN, WireGuard, SoftEther, etc. For this example, let's use OpenVPN.

2. Install and Configure the VPN Server:

• Follow the documentation of the chosen VPN server software to install and configure it on your dedicated server.

3. Enable Split Tunneling:

• For OpenVPN, you'll typically have a configuration file (usually server.conf). Edit this file to enable split tunneling.
• Locate the server.conf file and add the following line:perlCopy codepush "route <network_address> <subnet_mask>"
  Replace <network_address> and <subnet_mask> with the actual network address and subnet mask of the resources you want to access through the VPN.

4. Configure Client VPN Profiles:

• For each client that connects to the VPN, you'll need to configure split tunneling on their individual profiles.
• Open the client's OpenVPN configuration file (usually a .ovpn file) and add the following line:phpCopy coderoute <network_address> <subnet_mask>
  Again, replace <network_address> and <subnet_mask> with the appropriate values.

5. Restart the VPN Server:

• After making these changes, restart the VPN server to apply the new configuration.

6. Test the Configuration:

• Connect to the VPN from a client and try accessing both resources that should go through the VPN and those that shouldn't. Verify that the split tunneling is working as expected.

Important Considerations:

• Security: Be cautious when implementing split tunneling, as it may expose certain traffic to potential security risks. Make sure that you only allow the necessary traffic to bypass the VPN.
• Firewall Rules: Adjust firewall rules to allow traffic as necessary for both VPN and non-VPN resources.
• Logging and Monitoring: Implement logging and monitoring to keep track of the traffic that is going through the VPN and ensure that it aligns with your security policies.

Remember that the exact steps may vary depending on the VPN server software you choose, so refer to the specific documentation for the software you're using. Always test thoroughly and consider the security implications of your configuration.
