I've been reviewing the log file for my personal router/firewall WGR614v9 and, though I have 8 active hosts on the network, I keep seeing connections to port 46253 to one of the Windows7 hosts at 192.168.1.20. The router/firewall doesn't have any ports open explicitly and there is no port forwarding. Furthermore, there is Kaspersky installed with pretty much everything blocked off on the host itself. This keeps happening even when the host is not running anything.

Any ideas what this might be?

I've installed Wireshark on the host and see "Destination unreachable" responses by the host to the port 46253 UDP requests...

What I also don't get is why these requests make it past the router/firewall in the first place!

Try running netstat -b to see which executable is listening on those ports. It's possible it's an updater for one of your bits of installed software that Kaspersky has recognized as valid.
