Inner and outer Networks on Xen 3.0.3

[Anzi <anzi%dnainternet.net@localhost>]

Hi,

What is the best way to use xen so that dom0 (netbsd3.1) machine has 
several network cards and only on "managent interface". I mean that 
DomU:s may be on the dmz zone and dom0 is on the internal network? I 
think that it is possible with exporting nics as pci devices but is this 
operational yet?

Anybody has has better ideas?

I currently assigned and public-ip address for DOM0 and DOMU and used 
standard network-bridge vif. This has the downside that dom0 is then 
also publicly available (they are behind firewall).
DomU is an Fedora Core 6
