I think ipchains is disabled in the kernel anyway.
So I can't use it or ipfwadm
Only the option for IPTables I guess

What you said at the start is perfect, yet I disagree with what you said
about ipchains/iptables (or gosh does this end up in a discusion aka
learn pascal first then learn C ??? hehehehehe).
IMHO ipchains teaches you "wrong things" eg the way packets flow.
* Iptables has routing built in which makes a descision where
packets go not interfering with the input chain.
* In iptables the log target is better than the log rule.
* Iptables has the reject target with rules how to reject (icpm)
which is non existing in ipchains.
I would go straight to iptables, skipping ipchains.
When I started using iptables I had a few questions amongst
"why have two similar packages". Rusty (the maker of ipchains) ansered
that ipchains will be phased out; if you already have ipchains you
can stick with it for a while, but if you new go with iptables.

PS: (I went stright to C ;-)), skipping pascal)
