We decided to change hosts, because our old host wasn't doing much about the attack. We moved to Hypernia, but they too can't do much.

Quote:I am not seeing anything out of the ordinary on the .51 server. The DOS is probably taking advantage of game bugs and it's near impossible for us to block this sort of attack. The best tools you have are VAC and banning them. If you find any mods that may help prevent them crashing the server, we'd be happy to assist in setting that up.
The problem is it's not really an attack on the machine, just the individual game server, so traditional DDOS protection on the network is nearly useless detecting it and stopping it. Typically game DOSes send slightly malformed game data packets which the game server accepts but then later causes it to crash or lag out. It's extremely difficult to detect or block this kind of attack from the network side. Packet dumps of just data going to your server might not help either, as a few malformed packets out of millions would be impossible to locate.
Your best bet might be the mod community and game admin community who may have more relevant advice for your specific game.
