shared network vs isolated network

[Sonali Jadhav <so...@servercentralen.se>]

Hi,

I have deployed zone with Security groups disabled. I have few doubts,

1)      For getting shared network working is it required to have zone enabled with security groups?

2)      Why is that Public IP ranges added on Public NIC can't be used for shared network?

3)      Isn't it weird that we have to add public IP ranges for shared network on Guest NIC and for isolated network on Public NIC? I mean why two different NIC ? in the end its public network  traffic.

Hi, Sonali
1) no, security groups are not mandatory
2) 3) As far as I know public IPs (from public network) can be attached to
VM only with SNAT service. You can create public net with SNAT service. I
tried it when 4.2 was the last release but couldn't make it work. Maybe 4.4
doesn't have those bugs

Not really. Are you saying that public and guest networks should use IPs from the same pool? You do realize that networks and their IP ranges are categorized based on the traffic and not the network segment.
