Kill Switch Blocks Internet After App Crash

Problem

After the app crashes, the internet is blocked even though GateControl is no longer running.

Cause

The kill switch firewall rules were not cleaned up during the crash.

Solution

Easiest method: Simply restart the app — it automatically cleans up orphaned rules.

Manual cleanup: Open an admin command prompt (cmd) and run:

netsh advfirewall firewall delete rule name="GateControl_KS_Block_All_Out"\nnetsh advfirewall firewall delete rule name="GateControl_KS_Block_All_In"\nnetsh advfirewall firewall delete rule name="GateControl_KS_Allow_Loopback"\nnetsh advfirewall firewall delete rule name="GateControl_KS_Allow_WG_Endpoint"\nnetsh advfirewall firewall delete rule name="GateControl_KS_Allow_VPN_Subnet"\nnetsh advfirewall firewall delete rule name="GateControl_KS_Allow_DHCP"\nnetsh advfirewall firewall delete rule name="GateControl_KS_Allow_LAN_10_0_0_0_8"\nnetsh advfirewall firewall delete rule name="GateControl_KS_Allow_LAN_172_16_0_0_12"\nnetsh advfirewall firewall delete rule name="GateControl_KS_Allow_LAN_192_168_0_0_16"
