TeamSpeak server protection

[xlCristianVargas]

Good day to all


I request your collaboration so that they can recommend some protection from my server and I suffer a type of attaque that consumes me all my vps processor. As you will see below.

was filled with 20% to 120% capacity vps processor that give a 1core and I play to improve 2core. Since ts sounded bad and there was a packet loss up to 40%.

I appreciate any recommendation to increase security in my teamspeak server

Are you able to provide a tcpdump of the attack? But just let you know before, the most attacks cannot be filtered with your vps software firewall. You need to do that on network level. Because they often overload your networkcard (too much packets or size).
