How to Use Network Access Control to Restrict Network Access

Navigate to Desktop → Network Access Control

Click the Network Access Control Function Area

Select the Network Access Permission

Full Access: No network restrictions — fully open.

LAN Only: Only allows broadcast packets and internal addresses such as 172.x.x.x, 168.x.x.x, and 10.x.x.x to pass; all others are blocked.

China Only: Only allows Chinese IP addresses (including IPv4 and IPv6) to pass; all others are blocked.

Changes take effect after a restart.
