What Is Split Tunneling and Why Should You Care?
When it comes to Virtual Private Networks (VPNs), one of the coolest features you might not be using yet is split tunneling. Simply put, split tunneling lets you decide which parts of your internet traffic go through the VPN and which don’t. This is a game-changer because it gives you more control over your online experience. Instead of routing all your data through a VPN—which can sometimes slow things down or block access to local devices—you can pick and choose what stays private and what stays local. Whether you want to stream your favorite shows without lag, access local printers, or securely browse sensitive sites, split tunneling makes your VPN smarter, faster, and more flexible.
How Does Split Tunneling Work?
Understanding how split tunneling works doesn’t require a tech degree. Think of your internet connection as a highway. When you turn on a VPN, all your cars (data) are forced onto a secure, private road, which might be longer but safer. Split tunneling allows some cars to take the regular highway while others stay on the private road. This means for certain activities like gaming or accessing local network devices, your traffic won’t have to fight the congestion on the VPN route. Meanwhile, more sensitive activities like online banking or connecting to corporate networks remain protected.
Types of Split Tunneling in VPNs
There are a few ways split tunneling can be set up, and each offers unique benefits depending on what you need. The common types include:
- Inverse split tunneling: All your traffic uses the VPN except the selected apps or sites stay outside the tunnel.
- App-based split tunneling: You pick specific applications whose traffic should bypass the VPN.
- IP-based split tunneling: You select specific IP addresses or domains that shouldn’t use the VPN.
Knowing these options helps you customize your VPN to fit your lifestyle perfectly. For example, if you’re someone who works remotely but needs local access to home devices, IP-based or app-based split tunneling can be invaluable.
Step-by-Step Guide: How to Use Split Tunneling in VPNs
Now that you’re familiar with the basics, here’s a simple how-to guide on enabling and using split tunneling across common VPN platforms.
Step 1: Choose a VPN Service That Supports Split Tunneling
Not every VPN offers split tunneling, so your first step is picking one that does. Popular VPNs like ExpressVPN, NordVPN, and Surfshark feature split tunneling in their apps. Before signing up, check the provider’s features page or FAQs to confirm.
Step 2: Install and Open Your VPN App
Download the VPN app on your device and log in. Most apps place split tunneling settings under either “Settings,” “Preferences,” or “Network.”
Step 3: Locate Split Tunneling Options
Look for a menu item called “Split Tunneling,” “Bypass VPN,” or something similar. Depending on your VPN, the feature might have different names but performs the same function.
Step 4: Configure Which Apps or Websites Use VPN
In the settings, you will typically see options to add apps or websites into a list that either bypasses the VPN or forces the VPN connection. Choose based on your needs:
| Use Case | Recommended Split Tunneling Setup |
|---|---|
| Accessing local devices (printers, NAS) | Bypass VPN for these devices or apps |
| Streaming geo-restricted content | Route streaming apps through VPN |
| General browsing with faster speed | Bypass VPN for everyday browsers |
Step 5: Save and Test Your Configuration
Once you set your preferences, save the settings and reconnect the VPN. Test by visiting a site that should either be routed through the VPN or not. For example, run a speed test with the VPN on, then test again with your split tunneling rules active to see the difference in speed.
Benefits of Using Split Tunneling in VPNs
At this point, you might wonder, “Why go through the hassle? What’s in it for me?” Here’s what split tunneling brings to the table:
- Faster Internet Speeds: Since only some traffic routes through the VPN, you avoid unnecessary bottlenecks.
- Access to Local Network Devices: Easily print, stream, and use local services while staying protected online.
- Save Bandwidth: Limit VPN use to only apps or services that need encryption, reducing data load.
- Better Streaming Experience: Bypass VPN for streaming apps for less buffering and improved compatibility.
- Improved Privacy and Security: Keep sensitive apps under VPN protection without sacrificing performance elsewhere.
Common Mistakes to Avoid When Using Split Tunneling
While split tunneling is incredibly useful, some pitfalls can reduce its effectiveness or compromise your security. Here’s what to watch out for:
- Routing Sensitive Data Outside VPN: Avoid bypassing the VPN for apps where privacy matters to prevent leaks.
- Overcomplicating Settings: Don’t add too many exceptions, which can confuse traffic flow and cause connectivity issues.
- Forgetting to Update Routing Rules: Apps and websites change, so occasionally review your split tunneling list to keep it relevant.
- Not Testing After Changes: Always verify your setup by visiting IP checkers or streaming services to confirm routing.
Who Should Use Split Tunneling?
If you’re a regular VPN user, split tunneling can be a massive upgrade to your experience. Here are some types of users who benefit the most:
| User Type | Why Split Tunneling Helps |
|---|---|
| Remote Workers | Access corporate VPN while using local apps freely |
| Gamers | Reduce latency by bypassing VPN for game traffic |
| Streamers | Get better streaming speeds without losing privacy on important tasks |
| Privacy-conscious Users | Customize which apps need maximum security |
Split Tunneling and Mobile VPNs
Split tunneling isn’t just for desktops. Many mobile VPN apps now support it, adapting to how we use smartphones and tablets. For instance, you might want your messaging apps secured through the VPN but leave navigation or local weather apps outside the tunnel for faster updates. When configuring split tunneling on mobile devices, the steps are quite similar—look for the feature in the app settings and add apps accordingly.
Is Split Tunneling Safe?
A natural question arises: “Does split tunneling make me less secure?” The answer depends on how you use it. If you carefully choose which apps or websites bypass the VPN, you maintain solid security while enhancing convenience. But if sensitive data routes outside the tunnel, this could expose your information. Always think about what data you want protected and configure your split tunneling settings with security priority in mind.
Final Tips for Getting the Most Out of Split Tunneling
To wrap things up, here are a few tips to make split tunneling work best for you:
- Regularly review and update your split tunneling lists based on your online habits.
- Combine split tunneling with a reliable VPN provider that offers strong encryption and no-logs policy.
- Use IP-based rules if you want granular control over website access rather than bulk app options.
- Test your configuration periodically to ensure it behaves as expected.
Conclusion
Split tunneling is a powerful tool neatly integrated into many VPNs, allowing you to customize your internet routing for speed, convenience, and security. By learning how to use split tunneling in VPNs, you open the door to smoother streaming, faster browsing, and smarter remote working—all without sacrificing privacy where it counts. Remember, this feature isn’t about just turning your VPN on or off, but strategically choosing when and where to use it, making your online presence both flexible and protected. So next time you connect to a VPN, take a moment to try split tunneling—your internet experience might just thank you.
