2. Key Settings Overview
| Option | Recommended Value / Notes |
|---|---|
| Port | Leave as 7890 (default) unless that port is already in use. |
| Allow LAN | ON – Lets other devices on your LAN share the proxy port. |
| Log Level | info – Standard logging; switch to debug for troubleshooting. |
| IPv6 | ON – Enable if your ISP supports IPv6. |
| Service Mode | Install only if you need Clash to run as a Windows service. |

3. Recommended Best Practices
- Enable Allow LAN to share your proxy connection with other devices on your network.
- Enable IPv6 to future‑proof against increasing IPv6 adoption.

WARNING
If enabling TUN Mode causes connectivity issues, check for conflicts with other VPNs or virtual adapters and reboot your PC.
