The thing is how come there are so many different sorce Ips??

Also i noticed it started on friday @ 22:37 for 10 mins then started up again on sat @ 18:38 for 10 mins until i had to reboot (and then realised what happened)

A single machine probably can't send enough packets to bugger up a server. Get lots of machines sending lots of packets then you can cause a headache.

Dont know who would both little old me

Just doing ome googling most of those ips are CS servers it seems or link to CS in some way :confused:

It's much more likely it's a hyperactive firewall.

I had my router constantly sending me logs earlier today with dropped UDP packets from various sources, turned out it was Battlefield 2, when refreshing the online server list. U or someone else on your network been playing online games?

27015 and 27016 look like a HL or HL2 based game
