When you use a standard Virtual Private Network (VPN), all of your device traffic routes through an encrypted tunnel to a remote server. While this secures your connection, it often introduces friction. For remote workers, creators, and small business owners, an all-or-nothing VPN can block access to local network hardware like wireless printers, Network Attached Storage (NAS) drives, or smart home devices. It can also slow down everyday browsing speeds because data takes an unnecessary detour through a distant server.
Learning how to set up split tunneling vpn routing solves this problem. Split tunneling allows you to divide your internet traffic, sending sensitive applications through the encrypted VPN tunnel while routing regular browsing or local device traffic through your standard internet connection. This guide explores how selective routing works, what limits to consider, and how to configure it safely.

How to set up split tunneling vpn
Before you change any settings, it helps to understand what happens under the hood. A standard VPN client creates a single virtual network interface that intercepts all outgoing data packets from your operating system. When you configure selective vpn routing, you tell your VPN client to handle traffic selectively based on specific applications or destination IP addresses (subnets).
For example, you might route your web browser and enterprise applications through the VPN tunnel so your work activity remains private. Meanwhile, you can exclude your media streaming app or local file transfer utility so they use your direct local internet connection. This division helps conserve bandwidth and prevents common local hardware connection errors.
Evaluating the Limitations and Security Trade-Offs
While split tunneling improves convenience and speeds up local device communication, it introduces distinct security considerations. Any traffic that bypasses the VPN tunnel lacks encryption from the VPN provider. If an application is excluded from the tunnel, your Internet Service Provider (ISP) and local network administrators can see the destination addresses for that specific traffic.
For high-security corporate environments, administrators sometimes restrict split tunneling entirely to minimize data exposure. If you handle highly confidential client data or operate under strict regulatory frameworks, verify your organization’s security policies before changing your default routing configurations.
Step-by-Step Guide to Configuring Selective Routing
Most commercial VPN clients feature built-in split tunneling options within their settings menus. Depending on whether your provider uses app-based or IP-based routing, follow these general configuration steps:
- Open your VPN client application on your desktop operating system and navigate to the Settings or Preferences menu.
- Look for a tab labeled Connection, Advanced, or Split Tunneling.
- Enable the split tunneling toggle. Most modern clients offer two modes: App-based routing (allowing you to select specific programs) or IP-based routing (allowing you to specify particular subnets or IP addresses).
- If using app-based routing, click the option to add applications, then browse your system files to select the specific executable files you want to route inside or outside the tunnel.
- If using IP-based routing, enter the target local subnets or remote IP addresses you wish to isolate.
- Save your changes and disconnect, then reconnect your VPN session to apply the new network interface rules.
Testing Your Local Network and VPN Connection
After applying your new settings, verify that your configuration works as expected. Open a web browser and search for your current public IP address while connected to the VPN. It should display the location of your chosen VPN server. Next, test your local network connection by attempting to print a document or access a shared drive on your Local Area Network (LAN). If local devices respond normally while your external web traffic remains encrypted, your split tunneling configuration is successful.
Conclusion
Configuring a selective routing setup provides a practical balance between security and convenience. By keeping local hardware accessible and routing only essential traffic through an encrypted tunnel, you can optimize your network speed without sacrificing privacy for sensitive tasks. Always review your provider settings and security requirements to ensure your setup aligns with your operational needs.
Frequently Asked Questions
What is split tunneling in a VPN client?
Split tunneling is a feature that allows a user to route some of their internet traffic through an encrypted VPN tunnel while letting other applications or devices access the internet directly through their local network connection.
Why does a standard VPN block access to local printers or network drives?
A standard VPN routes all traffic away from your local area network and toward a remote server, which prevents your computer from communicating directly with local hardware like printers or NAS drives on your home or office network.
Is split tunneling safe to use for everyday browsing?
Split tunneling is generally safe for everyday use, but any traffic that bypasses the VPN is not encrypted by the provider and can be seen by your Internet Service Provider. It should be used selectively based on your privacy needs.
How do I verify that my split tunneling setup is working correctly?
You can verify your setup by checking your public IP address in a web browser to confirm it shows the VPN server location, while simultaneously testing access to local network devices like a wireless printer or local file share.
