Yep, but they're not deny'ed on the LAN side.

These are the NetBIOS ports, the broadcast address (again on the LAN)
would be something like 192.168.1.255:139. Again the rule won't deny
this.

255.255.255.255 is most likely an Class A DHCP request. For some
strange reason, since @HOME has been having random outages,
reports of tons of these requests have been made all over. Funny 
thing is the bulk of the ones I've been getting are from a private
class 10.6.1.x address. I just figured someone jacked up their Win2K
config.... seems to happen often around here. 

Aren't the /32 masks reserved for gov & university networks???
