Yup, and I seriously appreciate those that do that, but it's the small providers which inevitably end up screwing us over. Some small VPS company has a vulnerable server that someone makes a VPN on, and suddenly we get a wave of ban evaders. It ends up being a constant headache.
- dylz 10y agoIf it's default ports, you can just probe on login and deny it. We do this for a game I've admined for, and it's in the terms of service. Common L2TP, PPTP, etc.

- wbl 10y agoYou can ask the server to do it for you.
- MichaelGG 10y agoIsn't this a lost battle? Only remotely possible due to IPv4 being so limited? Do you allow normal users to get around banned IPs by buying a pass or something? (Then you can ban the pass, like 4chan.)
