[Xen-users] Remote management of DomU

[Alan Murrell <lists@xxxxxxxxxx>]

I currently have a Xen host server setup with three nics:

  eth0 -> hidden from Dom0 and assigned to my firewall domU
  eth1 -> assigned the the bridge br-lan0, which is then exported to the 
firewall domU for my LAN (handles both domUs and real machines on the LAN 
subnet)
  eth2 -> assigned to the bridge br-dmz0, which is then exported to the 
firewall domU for my DMZ (handles both domUs and real machines on the DMZ 
subnet)

My problem is this: I would like to be able to log into my Dom0 remotely, but 
do not want to put a 4th NIC in place to accomplish this; I'd rather do 
something like log into my firewall domU then from there SSH into Dom0, OR 
SSH to a different port and have the firewall domU port forward to the Dom0

I was thinking I may be able to accomplish this by using a dummy interface on 
both the Dom0 and the domU firewall that are tied together, but wasn't sure 
about how to configure this?  Would I give the dummy interface on the Dom0 an 
IP address then create a dummy interface on the firewall domU on the same 
subnet and put appropriate routing rulesin place? (I use Shorewall)  Or is 
there a better way to accomplish this?

Thanks, in advance, for your advice.

-Alan
