fixed ttl - most likely a single source, could even attempt locating it ...
also if the tcpdump is correct (no dropped packets) he is getting ~60
kp/s and ~30mbit/s - blockable by a one line iptables rule (ttl, id, length)

Yeah, if the enemy uses bot-net then its hard to push back, atm im hosted on a
2/2GB line so no probs there... Actually we had someone who found a way
breaking a 100/100mbit, so we put the police on the case since it half killed
our community. A year after (about.. christmas 2011 i think it was) they met in
court and the guy is now gone :-) but a year.. hope other countries are faster
than Denmark hehe

You can't stop bandwitdh oriented (UDP) DDoS attacks that fill up your
entire bandwidth. They have to be stopped at a higher level in the network,
ie. by your ISP.

blocks the ip right away for x timeSourcemod has a lot of stuff too that
blocks it Hope this helps as its working for me> Date: Wed, 23 May 2012

Thanks for the*only* reply :) This didn't help though. They're still
able to flood the IP/port.
You should let us know how you have blocked it. Maybe there's the mistake.
