Security alert from my router?

[#1]

Hi,
My Netgear router (admittedly not supplied by PN) has sent me 3 warnings today that its received a UDP packet looking at an IP address that is internal to home network?
UDP Packet - Source:219.84.126.94,45726 Destination:192.168.xxx.xxx,34311 - [DOS]
anybody familiar with this kind of thing?
