Thanks for your interest, but I was not uninformed. I just didn't
understand the whole concept of Firewall, but I do know all -almost all-
about configurations. You forgot to talk about screened hosts or screened
subnets, which allow the dual homed host to not to be dual - it's not
necessary since it's connected directly to the internal network and it has
nothing to do with packet filtering, just has to redirect the internal
traffic to a router which does the packet filtering tasks. Hence better
is to use a peripheral network to be the home of the bastion host, which
is isolated by two routers, one connecting to the internal network and the
other to the Internet.
I just don't know about configuring IN A REAL NET those items which are
part of the firewall. I would like to see some config files of a router,
or the file hosts.allow or hosts.deny, etc.
Thank you for your interest.
