Distributed Denial of Service Attacks

[Infinity∞]

Someone is always DDoSing me through Steam. Since Steam uses VoIP, all they need to do is call for 5 seconds to grab my IP Address. Is there anyway to stop the attacks besides changing my IP Address because it doesn't help. My Linksys router doesn't seem to block off IP Addresses.
My ISP is also very dim-witted, they think DDoS attacks are targeted on computers. I won't bother asking them again...

Your ISP knows far more about DDoSing then you do.

All I can say is get a decent Firewall such as Zone Alarm, or COMODO.

A simple solution is COMODO FIREWALL only.

I personally recommend Online Armor.

Great firewall.
