High severity log

Hi,

I got this in one of my logs…

Date/Time :2006-11-26 19:17:49
Severity :High
Reporter :Network Monitor
Description: DDOS Attack (ICMP Flood)
Duration: 20 seconds # of packets: 127 # of attackers: 2
Attacker(s): 85.236.101.41, 85.236.101.57
The firewall has switched to EMERGENCY mode.

I looked up those IP’s and they are both from Multiplay. (They rent out servers for gamers)
I’m a member of a clan and play BF2 and BF 2142.

This log isn’t serious is it?

I’ve had two more since that one, both with the same IP’s.
