Subject: Is my firewall safe?
Hi
I've just finished setting up a linux box to act as an internet gateway & firewall, tho i'm not sure whether it's secure. I have currently blocked all incomming CONNECTIONS from ports 0 to 1023 except for 20, 21 and 80 (as the machine is also being used for a web & ftp server). I know that this range of ports are used by services run as root, so should this be enough? I was considering blocking connections from 0 to 65535 but this would mean 'real' ftp wouldnt work for me and i'd have problems running Halflife multiplayer games - oh no!!!
Thanks,
<p><p>Andrew
