Yes, literally impossible. The barrier to entry for anyone on the internet to create a proxy or VPN to bypass your geofencing is significantly lower than your cost to prevent them.

I don’t even understand where this line of reasoning is going. Did you want a separate network blocked off from the world? A ban on VPNs? What are we supposed to believe could have been disallowed to make this happen?

I don't understand why you want to allow any random guy anywhere in the US but not people country hopping on VPNs. For your air machine infrastructure.

It's a bit weird that you can't do this simple thing, but what's the motivation for this simple thing?

Actually, the 140k Tor exit nodes, VPNs, and compromised proxy servers have been indexed.

It takes 24 minutes to compile these firewall rules, but the black-list along with tripwires have proven effective at banning game cheats. Example, dropping connections from TX with a hop-count and latency significantly different from their peers.

Preemptively banning all bad-reputation cloud IP ranges except whitelisted hosts has zero impact on clients. =3
