Easy to fix this. Get static IP at home, then blacklist tcp 27015, and pinhole only your static IP at home to that port.
If that’s no good, because you either can't get static at home, or you need to manage from elsewhere, install vpn server on your server, block traffic to tcp 27015, and vpn in to manage rcon, that’s how I am handling it. They would need to hack my vpn to get my server.

You should check into your network controls to make sure your ip4 settings dont allow for spoofing. The other thing would be to ban more then that single address. Ban his CIDR address instead. iptables -A INPUT -s 210.51.0.0/16 -j DROP That address is from China. You can look up any ip address via www.dnsstuff.com. If it cant find the information for you, it will point you to the appropriate resource like ARIN. _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlds_linux _______________________________________________ To unsubscribe, edit your list preferences, or view the list archives, please visit: http://list.valvesoftware.com/mailman/listinfo/hlds_linux
