Occasional port scan behind router, but port 0

[Adam Membrey]

I'm currently running a Netgear WGR614 wireless router with a cable modem, I
have the firewall enabled on the router however for my P2P program I have
port 4662 forwarded to my internal IP (192.168.0.3 reserved for my MAC
address on the DHCP server). I also run BlackIce PC Protection locally,
from time to time I receive a warning that I am subject to a port scan from
an external address (random) with the originating and destination ports
being 0.

Is this anything to be concerned about or just a few random connections
going awry with my port forwarding?

Adam,

port 0 is not and most likely will not be assigned to anything,
so I think there is no reason to worry. It looks very much like
a harmless defect somewhere, possibly in the router.
