Well, first of all this is an old post (last sept), and I learned much in the way of firewalls and networking since then. I configured a good ipchains firewall. I disregared iptables long before because it seemed too complicated for me. My kernel is 2.2.22 on Trustix Secure Linux.

I'd like to add an extra hardware-firewall at the border of my network. I'm not too serious about it, but it's worth a shot. I have an old 486 computer (100 mhz, 16 mb ram with Red Hat 7.0 installed). Is that a fast enough PC? If it's not, I won't bother. BTW, when I say "fast enough", I mean that I wouldn't see any noticable speed difference on the internet.
