Hi

This happened the second time to me now.

I wanted to play some Demigod, launched the game, played a nice pantheon game (3on0, slaughter mode) and joined an other game. After some time, Demigod crashed and my firewall fired the following message up:

Denial of Service "Jolt2 Attack" attack detected.

Description:
Jolt2 attacker floods illegally fragmented ICMP or UDP packets into your computer and causes your CPU utilization to be 100%

So I back traced this attack, and getting the following ip as the last ip in the route: 66.28.242.200.

The one, before this ip has the following name: StardockCorporation.demarc.cogentco.com

So I think, this NAT traversal method is identified as a DoS attack on firewalls, with high security settings (I´ve just changed some settings in order to be untroubled by this forced shut down

Ah, last but not least:

I´m using the Sygate firewall.
