        If you are using bridging and the connection to eth0 already supports 
all of these addresses, you should simply assign one address to each domU 
directly.  There is an ip= switch for the vif line in PV domUs, but I believe 
it is not for bridging.  That said, I think you want to remove the aliases and 
the IPs f9om dom0 and manually configure the eth0 in each domU just as you 
would a normal machine (with an IP, netmask, gateway, etc).  If the IPs can be 
used from dom0 and bridging is working properly, this should allow them to be 
used exclusively from their respective domUs.

Subject: [Xen-users] Xen 3.2 Setup advice pretty please

Hi all,

I have been trying various failing solutions so I turn to the gurus for 
guidance in times of trouble.

I have a Xen 3.2-1 server running on a Debian etch (2.6.18-6-xen-vserver-686) 
in a remote data centre.
I also have 5 public IPs in different ranges and only one NIC.

What I want to do is simple.  Have the applications running on my DomUs 
available to the internet.

Dom0 - Web proxy for routing to the correct Dom(2/3).
Dom1 - Mail
Dom2 - Web
Dom3 - Web

I'd like it as secure as possible.

I tried using IP aliasing on my NIC + bridge but that didn't work.
I tried nat but I can't seem to get the firewall to work properly.


In short:

                       |-> Dom0
WAN <--->   eth0   <---|-> Dom1
        91.111.100.50  |-> Dom2
        100.10.121.30  |-> Dom3
        98.66.100.125
        96.130.120.14
        95.85.140.121


If anyone has any advice at all, I'd greatly appreciate it.  I'm at a loss.

Thanks
