I have a little problem, since 3 day my server is attacked.
I have make a lot of research, and the only thing that i found is :
I think it’s a UDP flood.
My dedicated server is under attack only when my server Gmod is enable. And when i have bloqued all UDP with iptable, it stop to lag.
This the netstats -na when my server is not under attack :
And when it’s underattack , the 11000 is a 2XXXXX
But i really don’t know how i can stop it, i can’t stop it with a firewall because it’s on my server IP and port and i can’t see the IP who sended the packet …
If i can just see what is the packet sended or the IP who send this packet, it will be perfect but i have nothing …
So can someone give me any help please?
Sorry for my English,
A Gmod Lover
