In simple words
A regular VPN often routes all traffic through one connection. With split tunneling, routing rules can decide which traffic uses the VPN and which traffic does not.
Why it can help
- You can keep one VPN profile enabled instead of switching it on and off repeatedly.
- Some local services can continue to use the usual network route.
- The exact behaviour depends on the app, device and current profile.
Getting started
Use the instruction from the SmartTunnel bot for your chosen app. Do not change routing settings unless you understand the result.
