Applications through firewall

["Tanner, Robby" <TANNER Wardrop com>]

I had seen a web page not to long ago that listed applications known to work
through ipchains.  I think it also contained a little blurb on how to let
them through.

Specifically, I would like to know the mimimum requirement to let pcAnywhere
out of our system.  In the long term though, it would be nice to have that
web page bookmarked (I'm kicking myself for not having done that the first
time.

Cheers,
Rob
