<P> There are modules in the netfilter distribution called ipchains.o
and ipfwadm.o. Insert one of these in your kernel (NOTE: they are
incompatible with ip_tables.o!). Then you can use ipchains or ipfwadm
just like the good old days.</P>
<P> This will be supported for some time yet. I think a reasonable
formula is 2 * [notice of replacement - initial stable release],
beyond the date that a stable release of the replacement is available.
This means that support will probably be dropped in Linux 2.6 or 2.8.</P>
