Netgear Security Alert
Since setting up my router, i've been getting security alerts from it saying that the source of a 'UDP' packet was 87.86.189.16 (host name cns.sky.com). It's on various ports that this happens, and has (DOS) in brackets at the end of the line - Denial of Service attack I assume? But after googling that IP, it turns out that it's a sky DNS server? Is this normal? Or it it that someone else on the same network's trying to hack in, and the router can only report the DNS server address?

Not something I've ever had may be an idea to phone sky and ask them to investigate as that seems not right to me.

That's DNS traffic being falsely tagged by your router as hostile - which will effectively kill your connection, or at least stop you resolving a given site.
Don't know how differrent the Sky Netgears are from standard, but setting the firewall level to "Basic" (or even "Off") will stop that without hurting your security at all (NAT takes care of network attacks straight off the bat).
