How to detect VPN clients on my network?
Hello, I have a game server and we are trying to block VPN connection for many reasons, mainly because most hackers always use VPN.
I would like some hint/suggestion on how to detect if the IP is a VPN or even if the computer is connecting via a VPN (check can be placed on the client or server).
May be this can help https://www.lowendtalk.com/discussion/29827/vpn-ip-check/p1
For what game? I've seen many plugins for certain games already.
Private game not known
Block most of Hosting/VPS provider's IP.
In that case just create a module for the game server software to block IP ranges of the popular VPN networks.
Or you could just ipset iptables them out
The problem with most blocking systems is that they don't account for providers that provide both consumer and server hosting on the same ASN. For example, Korea Telecom does this.
Then you have VPNGate that provides P2P VPN services for free.
There are known VPN servers except that it's not easy to detect VPN. Known servers can be seen on free proxy sites or by browsing search engines. Blocking IP range can help. Detection of VPN is not so important.
Ask Netflix if you can borrow their script.
