Connection filtering
Connection filtering is under Settings. It is only in the menu when the account has connection filtering turned on, and when you can view VPN checks. Changing it requires the write permission.
Enforcement
Enforce VPN checks on join is the switch. Off means joins are still recorded, and players are not blocked for a VPN. On means a player over the detection threshold can be challenged or blocked.
Detection threshold is a percent. The helper on the field says players above this combined VPN score are challenged or blocked. Retries allowed and Cooldown (minutes) sit under it. Save enforcement settings writes those three values and the switch.
If the enforcement block is collapsed, Show settings opens it.
VPN providers
Add provider saves a key for one provider. Each provider can be added once per account. The chip counts how many are active. A provider has its own enabled switch.
Checks run when enforcement is on and at least one saved provider is enabled. Saved keys are what your servers use, in place of the platform defaults.
The denial text is a kick message. Bypass on a single player or address skips the check for that record only.
