What Is Split Tunneling and How Does It Work?
When you connect to a standard Virtual Private Network (VPN), all of your internet traffic is routed through a secure, encrypted tunnel to a remote server. While this ensures maximum privacy and security, it can sometimes lead to reduced internet speeds or prevent you from accessing local network devices like printers or smart home systems. This is where split tunneling comes into play.
Split tunneling is an advanced VPN feature that divides your internet traffic into two separate streams. One stream is routed securely through the VPN server, encrypting your data and masking your IP address, while the other stream is allowed to connect directly to the internet using your standard local network connection.
Think of it as having two different highways for your digital data. You can send your sensitive traffic—such as online banking, crypto trading, or confidential work communications—down the heavily guarded, encrypted highway. Simultaneously, you can send low-risk, bandwidth-heavy traffic—like streaming local content or downloading large game updates—down the regular, faster public highway. The process works seamlessly in the background, dictated by the rules and preferences you configure within your VPN application.
Why Do You Need Split Tunneling in a VPN?
The demand for split tunneling has grown significantly as users seek a balance between uncompromising security and optimal performance. There are several compelling reasons why you might need this feature in your daily digital life.
First and foremost is speed. VPN encryption, while essential for privacy, naturally introduces a slight overhead that can slow down your connection. If you are gaming competitively or streaming 4K video from a service that doesn't require geo-unblocking, routing that traffic outside the VPN can significantly improve latency and bandwidth availability.
Secondly, split tunneling provides access to Local Area Network (LAN) devices. When a traditional VPN is active, it places your device on a completely different virtual network, effectively cutting you off from local resources. With split tunneling, you can remain connected to your local Wi-Fi to print documents, cast videos to your smart TV, or access local file servers, all while keeping your web browsing secure.
Finally, some online services, such as banking portals or local delivery apps, often block known VPN IP addresses as a fraud prevention measure. Split tunneling allows you to exempt these specific apps from the VPN connection, ensuring you can use them flawlessly without having to disconnect and expose your entire device to potential threats.
What Are the Types of Split Tunneling?
Not all split tunneling features are created equal. Depending on the VPN provider and the operating system, there are a few different ways this technology is implemented to suit varying user needs.
- App-Based Split Tunneling: This is the most common and user-friendly type, especially on mobile platforms like Android. It allows you to select specific applications that should either always use the VPN or always bypass it. For example, you can set your mobile browser to use the VPN while allowing your local weather app to bypass it.
- URL-Based or Domain-Based Split Tunneling: Instead of selecting whole applications, this method allows you to specify certain websites or domains to be routed through or outside the VPN. This is primarily found in browser extensions or advanced desktop applications.
- Inverse Split Tunneling: This approach reverses the default behavior. Instead of routing everything through the VPN by default and choosing what to exclude, inverse split tunneling routes everything outside the VPN by default, and you only select the specific apps or websites you want to protect. This is ideal if you only need a VPN for a handful of highly sensitive tasks.
Split Tunneling vs. Full Tunneling: Which Is Better?
Deciding between split tunneling and full tunneling ultimately depends on your specific use case, threat model, and priorities. Full tunneling routes 100% of your device's traffic through the VPN, providing a blanket approach to security. Let's compare the two methods to help you decide which is better for your situation.
| Feature / Concept | Split Tunneling | Full Tunneling |
|---|---|---|
| Security Level | Selective (Only routed traffic is encrypted) | Maximum (All traffic is encrypted) |
| Connection Speed | Faster for bypassed traffic | Can be slower due to total encryption overhead |
| Local Network Access (LAN) | Yes (Printers, smart home devices remain accessible) | No (Generally blocks access to local devices) |
| Bandwidth Usage | Conserves VPN bandwidth | Consumes more VPN bandwidth |
| Setup Complexity | Requires manual configuration of rules/apps | Simple (One click to protect everything) |
| Best Use Case | Multitasking, gaming, local streaming | Public Wi-Fi, highest privacy needs, circumventing censorship |
As the table illustrates, split tunneling offers flexibility and performance, while full tunneling provides peace of mind through absolute coverage. For most modern users, having the option to use both as needed is the ultimate solution.
Is Split Tunneling Safe to Use?
When discussing VPN features, security is always the top concern. The short answer is yes, split tunneling is safe, provided you understand how it works and configure it correctly. However, it does introduce a layer of complexity to your security posture.
Because split tunneling explicitly leaves some of your traffic unencrypted and exposed to your Internet Service Provider (ISP) or network administrator, you must be absolutely certain that the apps or websites you choose to bypass the VPN do not handle sensitive data. If you mistakenly allow a confidential work application to bypass the VPN while on a public Wi-Fi network, that data could be intercepted by malicious actors.
To maintain maximum safety while using split tunneling, adhere to a strict rule of thumb: default to routing everything through the VPN, and only exclude applications that you know are low-risk or strictly require a local connection. Furthermore, ensure your VPN provider has a robust infrastructure that prevents DNS leaks even when split tunneling is active, so your browsing requests remain private.

Frequently Asked Questions
No, in fact, it can improve speeds for certain tasks. By routing bandwidth-heavy, low-risk traffic outside the VPN, you free up resources and avoid the encryption overhead for those specific applications or websites.
While you can use split tunneling on public Wi-Fi, it is generally recommended to use full tunneling in untrusted environments. Bypassing the VPN on public Wi-Fi leaves that specific traffic vulnerable to snooping and interception.
Yes, Unlimited VPN for Android fully supports app-based split tunneling. You can easily configure which apps use the secure WireGuard tunnel and which bypass it directly from the app's settings menu.
Traditional VPNs route all your traffic to a remote server, effectively disconnecting you from your local network. By enabling split tunneling, you can allow local network traffic to bypass the VPN, restoring your connection to printers and smart devices.
