Want the security of a VPN without sacrificing speed for local browsing or access to local network devices? Enter VPN split tunneling, a powerful feature that lets you selectively route your internet traffic, choosing precisely which applications or websites go through the VPN tunnel and which use your regular internet connection. This gives you granular internet traffic control and optimizes your VPN usage for various scenarios.
This article will explain what split tunneling is, how to use it, and the numerous benefits it offers. We'll guide you through understanding and configuring selective VPN connections to tailor your online experience and maximize both security and performance.
What is VPN Split Tunneling and How Does It Work?
Imagine your VPN as a secure tunnel that all your internet traffic usually passes through. VPN split tunneling creates a "split" in this tunnel, allowing you to choose which traffic takes the secure VPN route and which traffic bypasses the VPN and goes directly through your regular internet connection.
Here's a breakdown of how it works:
Regular VPN Connection (Without Split Tunneling): All your internet traffic – from all applications and websites on your device – is routed through the VPN server, encrypted, and then sent to the internet.
VPN Split Tunneling (Selective Routing): You configure your VPN app to specify which applications or websites should use the VPN connection and which should bypass it.
VPN Tunnel Route: Selected applications or websites have their traffic routed through the VPN tunnel, benefiting from encryption and IP address masking.
Direct Internet Route: Unselected applications or websites bypass the VPN and connect directly to the internet using your regular IP address and ISP connection.
Benefits of VPN Split Tunneling: Tailoring Your Connection
Split tunneling offers a range of advantages, allowing you to choose which traffic goes through the VPN and optimize your online experience:
Increased Speed and Bandwidth: VPN encryption and routing can sometimes slightly reduce internet speed. By routing only sensitive traffic through the VPN and allowing bandwidth-intensive activities (like streaming, gaming, or large downloads) to use your regular, unencrypted connection, you can potentially increase speed and conserve VPN bandwidth for tasks that truly need it.
Access Local Network Devices and Services: When connected to a VPN, you might lose access to devices on your local network, such as printers, network-attached storage (NAS) devices, or local servers. Split tunneling allows you to access local network resources while still maintaining VPN protection for other online activities. You can route local network traffic directly while sending internet-bound traffic through the VPN.
Targeted VPN Protection: You might not need VPN protection for all your online activities. Split tunneling allows you to target VPN protection to specific applications or websites that handle sensitive data or require enhanced privacy, while allowing less sensitive traffic to use your regular connection for speed and convenience.
Bypass Geo-Restrictions Selectively: You can use split tunneling to access geo-restricted content (e.g., streaming services) through the VPN while simultaneously accessing local websites or services that might not work well with a VPN (e.g., local news websites, online banking in your home country).
Use Cases of VPN Split Tunneling: Practical Applications
Here are some common use cases where split tunneling proves particularly useful:
Streaming Local Content While Using VPN for Other Activities: Want to watch Netflix US through your VPN but still access local news websites or streaming services that are region-locked to your actual location? Split tunneling allows you to route Netflix traffic through the VPN while directing local website traffic directly.
Accessing Local Network Devices While VPN Connected: Need to print a document on your home network printer while simultaneously using a VPN for secure browsing? Split tunneling lets you route printer traffic directly to your local network while sending web browsing traffic through the VPN tunnel.
Gaming and VPN Simultaneously (Selective Protection): Want to use a VPN for secure gaming to protect against DDoS attacks but don't want the potential latency increase for all game traffic? You can route your web browsing and other applications through the VPN for security while allowing your game traffic to bypass the VPN for optimal speed and ping.
Downloading Torrents While Browsing Locally (Selective Privacy): Want to use a VPN for secure and private torrenting but don't want to slow down your general web browsing? You can configure your torrent client to use the VPN while your web browser and other applications connect directly.
Working Remotely with Company VPN (Selective Access to Company Resources): In some corporate VPN setups, split tunneling might be used by IT departments to allow employees to access company resources through the VPN while general internet browsing and non-work-related traffic bypass the VPN for better performance on personal tasks. (Note: This use case is often controlled by company IT policies and may not be configurable by individual users).
Setting Up VPN Split Tunneling: Configuration Guide
The process of setting up split tunneling varies slightly depending on your VPN provider and VPN application, but here are general steps:
Access Your VPN App Settings: Open your VPN application and navigate to its settings or preferences menu.
Look for "Split Tunneling" or "Routing" Options: Search for settings labeled "Split Tunneling," "Split Routing," "App Exceptions," "Website Exceptions," "Routing Rules," or similar terms. The exact wording varies between VPN providers.
Choose Split Tunneling Mode (if applicable): Some VPNs might offer different split tunneling modes, such as:
App-Based Split Tunneling: You choose specific applications that will use the VPN or bypass it.
URL/IP-Based Split Tunneling: You specify websites (URLs) or IP addresses that will use the VPN or bypass it.
Select the mode that best suits your needs. App-based is often more convenient for general use.
Configure "Excluded" or "Included" Lists:
"Exclude Apps/Websites" (Most Common): You create a list of applications or websites that you want to bypass the VPN and use your regular internet connection. All other traffic will automatically go through the VPN tunnel.
"Include Apps/Websites" (Less Common): You create a list of applications or websites that you want to force to use the VPN connection. All other traffic will bypass the VPN.
Add Applications: If using app-based split tunneling, you'll typically see a list of installed applications. Select the applications you want to exclude or include based on your chosen mode.
Add Websites/IPs: If using URL/IP-based split tunneling, you'll usually need to manually enter website URLs or IP addresses that you want to exclude or include.
Save Your Configuration and Test: After configuring your split tunneling settings, save the changes and connect to your VPN. Test your setup to ensure it's working as expected.
Verify VPN Routing: Check your IP address using a website like "WhatIsMyIP.com" while using an application or website you expect to be routed through the VPN. It should show the VPN server's IP.
Verify Direct Routing: Check your IP address again while using an application or website you expect to bypass the VPN. It should show your real IP address.
Test Local Network Access: If you configured split tunneling for local network access, verify that you can still access devices on your local network while the VPN is connected.
