Subject: tcp/udp port numbers

Does anyone have a complete list of port numbers? I have a firewall
where I am seeing traffic on port 161 but haven't been able to
track it down. All of the hosts behind the firewall are NT boxes
and I'm thinking that it's related to WINS. It seems that when I
do a Network browse it starts firing off packets to all IP addresses
on the other side of the firewall via udp port 161. It seems to start
at one IP and then increment bit wise.

I've found some web pages that list port numbers but they're pretty
much the same as unix:/etc/services.
