You can also try turning on tcp_syncookies and adjusting the network timeouts/buffers. But if it 's just a ton of of bandwidth being leveraged against you, iceman47's right in that there isn't much you can do. If that's the case, call your ISP and ask them to help you out. Usually they'll either work with you to filter stuff out farther upstream or they'll work with other ISPs to try and stop it at the source (if that's even possible).
