Split tunneling: when and why to use it

Split tunneling lets you route some traffic through your VPN while other traffic goes directly to the internet.

When to use split tunneling:

• Local network access: Access devices on your home network
• Banking apps: Some banks block VPN traffic
• Gaming: Reduce latency for online games
• Streaming: Access local content while protecting other traffic

How it works:

• App-based: Choose specific applications to exclude from VPN
• IP-based: Route traffic to specific IP ranges outside VPN
• Domain-based: Exclude specific websites or domains

Security considerations:

• Reduced protection: Excluded traffic isn't encrypted by VPN
• DNS leaks: Excluded apps may use your ISP's DNS
• IP exposure: Your real IP may be visible for excluded traffic

Configuration tips:

• Be selective: Only exclude what's absolutely necessary
• Test thoroughly: Ensure excluded apps work as expected
• Monitor for leaks: Regular DNS leak tests are important
• Consider alternatives: Sometimes it's better to disconnect VPN entirely

Advanced users: Some VPNs allow custom routing rules for fine-grained control.
