What is the difference between system proxy and TUN modes? How to choose
The more "advanced" the two modes are, the better. An approach that meets the needs of the current application and has fewer conflicts is usually more appropriate.
Before you start
Operation steps
- 01
How system proxy works
The client modifies the HTTP/HTTPS proxy setting of the operating system. Applications such as browsers that follow the system proxy will use it. Some games and command line programs may ignore it.
- 02
How TUN works
The client creates a virtual network interface to take over IP traffic at a lower level, which has greater coverage and is more likely to conflict with VPN, virtual machines, filters, and corporate network policies.
- 03
Daily browsing priority system proxy
When only a browser and common desktop applications are needed, system proxy is usually simple to configure and easier to exit and restore.
- 04
Use TUN when the application does not use proxy
When the target application clearly does not comply with system proxy, and the system allows the installation of network extensions or drivers, then enable TUN.
- 05
Avoid repeated takeovers
Do not run multiple TUN/VPN tools at the same time; when switching modes, first close the old mode and confirm network recovery.
After completion, check like this
- Identify which applications require proxy
- Run only one primary network takeover tool
- proxy settings restored after exiting
- TUN driver or permissions are normal
FAQ
Will TUN make it faster?
uncertain. It mainly changes the traffic takeover range and does not directly guarantee the line speed.
Which one does the mobile version belong to?
Android and iOS usually use the system VPN interface, and the experience is closer to the global takeover of TUN.
