We had recent DOS attack, ie yesterday and our main MT box bombed at about 250k connections....
What kind of hardware & line are we talking about here?
It was running at about 5mbps (The MT box restricts local to 5mbps), as the traffic was running around our 10mbps wireless network and going out to the internet.
This is running on a P200 :) Lookin at the CPU Usage, it was gradually going up as the traffic increased and eventually couldn't handle the load. I suspect the p2p mangle rules I have bombed it, as they are very CPU intensive.
I will be upgrading the box soon to stop this happening again.
