Subject Re: Remote Cloudstack Management Server and public IPs
Date Wed, 20 Feb 2013 00:54:15 GMT
Not familiar with OVH, but in general 'advanced' networking in CS is
challenging without VLANs. Do you have VLANs available?

What do you plan on using your CS for? I'd say there's a minimum of 3
"public ip" needed (assuming you are using advanced networking): 1 each
for the system vms and 1 for the virtual router.

Assuming you have VLANs (let's say the range is 100-200), you could use
one VLAN for the public ips. These 'public ips' can be non-RFC1918
addresses by the way.
