Subject Re: Cloudstack using without virtual Router
Date Thu, 05 Feb 2015 22:51:24 GMT

actually we have on our Ovirt Machines 2 Network interfaces, 1 for
Management network an 1 for the guest systems.

If we deploy a new Machine they become automatic a new
DHCP address from the Cisco router (between and /24).

After installation from our OS we change it manually to an other IP.
(e.g. Public for Company - /24, or Internal
for team - /24)

The IPs are in the same VLAN and IP range.  In front of the router a
firewall manage the access for the company.
A full automatic configuration from the Virtual router is not possible.
The address, that we should use for the company-wide access, are defined
by an other team.

Kind Regards,
