Proxy Block

Good morning family, in my server, I have only IP control, I do not have HWID, and the players is using a lot of proxy to login more chars, how can I block these connections? maybe block the ports of proxy socks? any solution? I use free SR_Filter

Thank you all!

Go through some public proxy lists and block the IPs in your machines firewall.

But, need take one by one? add all?

I'm not familiar with administrating windows servers. I guess you can use the Powershell-thing to add all the IPs automatically.
