I thinking about using PCI passthrough to dedicated a domU as firewall.

I understand PCI passthrough concept. When done, my domU will see
network card and the dom0 won't any more. So I'll be able to filter all
trafic from outside, since it will go through network domU.

Then, how will I be able to connect other domU (and maybe dom0) to the
network domU ?

In a normal way, creating domU makes dom0 creating vif interfaces and
bridge (in my configuration) it. But once netowkr will be isolated in a
specific domU, dom0 won't be able to interact with it, will it ?

How many network cards do you have in this computer? I think you'll need minimal 2 nics. One for dom0 and domU (vif) to communicate and one for PCI passthrough. As you understood right, dom0 won't see the PCI passthrought nic.

Any link/help/explanation appreciated.
