Understand TUN mode in Clash Meta / Mihomo clients, including use cases, permissions, and common errors.
Content reviewed: 2026-08-21
Who it is for
Users who need more applications to use the client, or whose target app ignores the system proxy.
Prerequisites
- The client and core must support TUN
- Understand that TUN changes the system network path
- Prepare administrator or VPN permission
Usage steps
- 1
Confirm the profile works in ordinary system-proxy mode first.
- 2
Read the client notes, grant required permissions, and enable TUN.
- 3
Test the browser, terminal, and target app while watching logs and DNS behavior.
- 4
If conflicts appear, disable TUN and return to the known-good system proxy mode.
Common issues
Why not enable it immediately?
TUN has a wider scope; verifying the basic profile first narrows troubleshooting.
