Hi,

I'm running RedHat Enterprise Linux 4 (RHEL4) on my Server and I use XEN for
virtualizes my Firewall (based on IP-COP) on the same machine.
The problem now is hat XEN associates always eth0 of domU with my NIC (eth0)
on dom0.
When I want to use my dom0 as DMZ host, I have to associate eth0 in my dom0
with eth1 in my domU as shown below. The eth0 in my domU should be a
physical interface in my system.

Dom0                            domU
Eth0            <--->           eth1
                                eth0            <--->   Physical Interface
(00:13.0)

How can I configure XEN's network in this way?

In short - assuming you use default settings..

* Remove dom0's eth0 and domU's eth1 from default bridge xen-br0.

* Create a new bridge and attach dom0's eth0 and domU's eth1 to it. Assign ip address accordingly either to the new bridge or the dom0's eth0.

* Leave domU's eth0 on the default bridge xen-br0 for outside network access.

Thanks,
Mike
