Can someone give me a plain text outlook on where the 2 firewalls
connect. I believe it is as follow:

Internet Router to that hub ->

Hub - exFW(public) / exFW(private) - hub(dmz hub) - inFW(private??) /

inFW - to LAN switch

The external firewall does not connect to the lan switch correct? Will
internal firewall have a public ip? The DMZ will be NATed..

sorry for all the questions guys.. just trying to get a real good
understanding of this..
