Mandrake 9.0 > Control Centre > Shorewall
I am a bit confused here. I have loaded Mandrake 9.0, and have run Mandrake Control Centre as root. In the security tab, I checked "Firewall" and "Shorewall" was installed. A number of checkboxes then came up with the following options:
Everything (no firewall)
Domain Name Server
POP and IMAP server
Checking any of these allows internet access.
I have tried all the HOWTOs which give long and dare I say boring stuff on setting .conf files, but all I want to find out is this (and I can't see the wood for the trees):
As my computer is just a personal computer which I use to connect to the net, and I do not run any services from my computer, can I just leave everything unchecked?
(I do have CUPS installed but not via a network)
