That is my misunderstanding, then; I had read that in another post while
I was searching for Xen + DomU firewall setups.

Correct.

Will the domU''s NIC (eth0, configured through DHCP) get the IP address
from the ISP or from the DHCP server I currently have on my network?

My host machine has three NICs. I currently have the following bridges
and mappings created:
xen-br-pub -> eth0 (will be the Internet connection)
xen-br-lan -> eth1 (will be my private network machines)
xen-br-dmz -> eth2 (will be publicly-accessible machines)
All three NICS are currently "assigned" to dom0, but I want to assign
all of them to the firewall and hide them from domU. If I do this, will
I still need to create the bridges?
Once I have all three NICs assigned to the firewall domU, I am planning
to create another brdige + dummy interface:
xen-br-adm -> dummy0
which will connect to a corresponding dummy interface on the firewall so
I can log into domU remotely to manage the different domains, or setup a
new one, if necessary.
