VPN Split Tunneling Explained

Sometimes you want VPN protection for one thing but not another — encrypt your browser while still printing to your home printer, or protect downloads while your banking app uses your real IP. That's exactly what split tunneling lets you do. Here's how it works, when to use it, and the trade-offs to keep in mind.

What Is Split Tunneling?

Split tunneling lets you route some of your traffic through the encrypted VPN tunnel while letting the rest connect to the internet directly. Instead of all-or-nothing, you choose which apps or destinations use the VPN and which bypass it. New to VPNs? Start with what is a VPN.

Types of Split Tunneling

• App-based: Pick specific apps to route through (or around) the VPN.
• URL/domain-based: Send certain websites through the tunnel and others direct.
• Inverse: Everything uses the VPN except the apps you exclude.

Benefits of Split Tunneling

• Faster where it counts: Bandwidth-heavy but non-sensitive traffic skips the encryption overhead.
• Local device access: Reach printers, smart-home devices, and NAS drives while still protected elsewhere.
• Avoid "logged in from abroad" issues: Let banking apps use your real local IP.
• Selective protection: Encrypt only the activities that need it.

When to Use It

1. Printing or casting to local devices while your browser stays on the VPN.
2. Accessing a banking app that flags foreign IPs, while torrenting safely through the VPN.
3. Streaming local services that block VPNs, without disconnecting protection for everything else.
4. Reducing load on the tunnel for large, non-sensitive downloads.

The Security Trade-Off

Convenience has a cost: any traffic you route outside the tunnel is unencrypted and exposes your real IP. Never exclude sensitive activity, and be cautious using split tunneling on untrusted public WiFi. For maximum privacy, pair it with a kill switch on the apps that stay protected.
