Subject:   What uses Port 137-NETBIOS Name Service?

I am getting the following denial in my IPFW log:

Aug 26 08:53:51 gateway /kernel: ipfw: 3200 Deny UDP 207.195.152.19:137
208.149.231.82:137 in via xl1

xl1 is my outside net
208.149.231.82 is my address of xl1
Rule 3200 is "deny log udp from any to any" which is my final rule.

I have a Windows NT Server inside my network, running NETbeui protocols. I
appear to be getting these requests from outside.

What uses port 137? Nobody on the network seems to be complaining that they
can't do stuff, so I am inclined to let it go, and keep denying the packets.
Is there a reason I should be letting these packets through?

Does anybody hava any thoughts on this?

Thanks
