In the “Allowed IPs” field, enter the IP addresses or networks that you want to bypass the VPN. You can use a comma to separate multiple entries.

macOS

Open the Terminal application.

2. Type the following command

“`sudo wg-quick edit wg0“`

3. Add the following line to the [Interface] section

“`AllowedIPs = 192.168.1.0/24, 10.0.0.0/8“`

Save the file and restart WireGuard.

Once you have configured WireGuard split tunneling, you will be able to access local resources and devices while still enjoying the security and privacy benefits of a VPN.

Use Cases for WireGuard Split Tunneling

WireGuard split tunneling offers a unique solution for users seeking flexibility and security in their VPN configurations. It allows specific applications or traffic to bypass the VPN tunnel while routing the remaining traffic through the secure connection.

This approach provides several advantages in various scenarios, including:

Accessing Local Resources

Split tunneling enables seamless access to local resources on the same network as the VPN connection. For instance, a user connected to a VPN for secure remote work can still access printers, file servers, and other devices on their local network without disrupting the VPN’s protection.

Performance Optimization

By excluding specific applications from the VPN tunnel, split tunneling can improve performance for those applications. For example, a user streaming video or playing online games can bypass the VPN for those applications, reducing latency and buffering issues while maintaining VPN protection for other sensitive traffic.

Security Enhancement

In certain situations, split tunneling can enhance security by isolating specific traffic from the VPN tunnel. For instance, a user accessing sensitive corporate data via a VPN can exclude personal browsing traffic from the tunnel, minimizing the risk of exposing corporate data to potential threats.

Advanced Split Tunneling Techniques

WireGuard offers advanced techniques to configure split tunneling, enabling granular control over traffic routing. These techniques include:

Multiple Network Interfaces: Using multiple network interfaces allows for finer control over traffic routing. Assign specific interfaces to the WireGuard tunnel, while excluding others, enabling selective routing of traffic.
Custom Rules: WireGuard Application advanced configuration options allow for the creation of custom rules. These rules specify conditions based on source/destination IP addresses, ports, or protocols. Traffic matching these conditions can be selectively routed through the WireGuard tunnel or excluded from it.

Example: Configuring Custom Rules

Consider a scenario where you want to route all traffic from a specific application through the WireGuard tunnel, while excluding traffic from all other applications. To achieve this:

1. Identify the IP address or port range used by the application.
2. In the WireGuard configuration file, add a rule using the “AllowedIPs” directive:

AllowedIPs = 0.0.0.0/0, ::/0 except 10.0.0.0/8

Specify the IP address or port range of the application after “except.”

This rule allows all traffic except traffic from the specified IP address or port range to pass through the WireGuard tunnel.

The application traffic will be routed through the tunnel, while all other traffic will be excluded.
