ipfwadm/ipchains

I am helping our local school district set up linux servers as POPS so
people can dial in using PPP and access some specific servers in our
WAN.

I've got PPP working fine and now need to add firewall rules to limit
access to only a short list of servers.

It's not totally clear to me how to use ipfwadm to do this...

Also, I am considering moving to slink and kernel 2.1.125 and using
ipchains instead. It looks simpler and I would like to learn just one
tool, if possible.

Anyone have any comments/help?

Thanks,
ml
