suggestions on a good firewall

["Beaney, Derek" <Derek.Beaney () usa xerox com>]

im planning on making a firewall for my home system.. I am running windowsXP
/ SuSE 8.1 dual boot  what I want to do is set up another computer to act as
a firewall for my main system. what I want this to do is to be able to
control what enters and leaves my system  with a way to set up permissions.
preferably I would like to have a firewall running on either a Linux or Unix
os ... no m$ =) tia
