Why are there always TWO blank lines between every line you type? Isn't
that just a little weird? :)

Run "ipfwadm -Mln" and look at the list of masqueraded connections. You
will probably find that it is a huge list, and the port numbers will
give you some clue as to what network protocol is requesting such a huge
number of ports.

For reporting Masq problems, your hardware really isn't relevant. :)

The netmask isn't important either, although if you get it wrong, you of
course will see some problems that aren't all that related to masq. :)

You probably have some new network software installed that is sending
out massive amounts of traffic and overloading your masq server. You
need to find out what it is (by listing out the masq traffic) and
putting a stop to it. It's probably ICQ, or QuakeWorld, or GameSpy, or
something like that.
