Hello All

XEN newbie here.

If I install minimal linux for XEN in dom0 and a periphery firewall in
domU and other applications in other instances of domU, is it possible
to restrict/bind the network card to domU having periphery firewall
and from there forward packets for dom0 or for other domUs?

Is this possible? If so, is it secure? Or does dom0 always have direct
access to Network Card and needs a separate firewall? And packets will
always route from dom0 to all domUs ?

What are the issues involved?

With best regards.
