I don't know anything about shorewall, so I can't help you there. I
can confirm your guess - you want to allow all UDP/TCP ports from all
the hosts you are going to be using with LAM. Well, you can safely
block all ports below 1024, but all non-reserved ports should be open.
Good luck configuring shorewall.
