I did a clean install on a Sun Sparcstation 4 to use this machine as a gateway and firewall (and perhaps some other small network related tasks).
I have most experience in working with 2.4 kernel based systems. I use Shorewall, an iptables based firewall on machines that support 2.4. I can't seem to find any kernels other than 2.20 for this architecture. Is it impossible or discouraged to use 2.4 on an old Sun machine like mine? I don't mind compiling a new kernel if it should potentially work. I seem to be able to apt-get shorewall. Is iptables back-ported? What other shorewall like solutions can I consider for an install once, never mess with kind of system? As you may have noticed I am not very knowlegeable about iptables/chains and what have you, but I want to secure my local network. I considered OpenBSD on the SS4 but since that os is completely new to me I'd rather stick with Debian. I felt safe, hopefully not unwisely so, with shorewall on my intel system. Please advise. Bob
