Yes, a "firewall" works with just a few netfilter commands, but it is
not just that :)

And the iptables man page... is hard to memorize just its the full
content/modules/options.

What about kernel sysctl for example ? there is a whole "net"
subsystem of kernel variables (sysctl -a | grep net) the documentation
for that is included with the kernel sources and sparse on the
internet...

What about logrotate and rsyslogd config ? What about the subnets arp
changes monitoring ? etc etc...
