Sorry, I have companies to run so I am delayed
in answering my PLUG mail :)

Only 1 firewall needed.

UGLY ASCII ART FOLLOWS:          | |--> Host1  
                                 |H|--> Host2
DSL router <--> Linux Firewall <-|U|--> Host3
                                 |B|--> Host4

Configure the DSL router to only accept connections from
the Linux Firewall.
Configure the Hosts to only talk to the firewall.
The firewall will have 2 Ethernet cards, one for each network segment.
Sleep better at night.

I have a 4 port DSL modem and only use 1 port in a configuration
similar to the one above.
