Hi guys
for a little time my ts3 suffer light ddos attakcs. I've done tcpdump and investigated it with whiteshark. i have to drop all conecctions length of 0-141
I tried this guide but \/ doesn't want to fit iptables rules.
iptables -A PREROUTING -t raw -p udp --dport 9987 -m length --length 0:141 -j DROP
Should i use sth like iptables -I INPUT-p udp --dport 9987 -m length --length 0:141 -j DROP or sth?
Also what comamnd i should use to block spec IP connecting to ts3 port?
It attaks my ts3 ports only cause all my websites ftp and other services working correctly, even ts3 is up but no one is able to connect cause of overload of packets.
Thx for advice
