Hello,
i added a zone with advanced network with following network
configuration on CS 4.2 but i was not able to setup same IP class on
public traffic ( of system vm ) and guest traffic ( of guest vm ).
Scenario
Servers with VMware ESXi 5.1 have multiple nic:
2 nic connected to physical internet switch ( vSwitch0 standard )
2 nic connected to physical private switch ( vSwitch1 standard )
On CS i create a zone with advanced network and 5 physical interface:
1 physical interface for Public traffic connected to vSwitch0 ( i think
it's system vm public traffic ).
1 physical interface for Guest traffic connected to vSwitch0 ( i think
it's guest vm public traffic ).
1 physical interface for Guest traffic connected to vSwitch1 ( i think
it's guest vm lan traffic ).
1 physical interface for Storage traffic connected to vSwitch1 ( i am
sure it's storage traffic for snapshot, deploy and so on ).
1 physical interface for Management traffic connected to vSwitch1 ( i am
sure it's for system vm traffic and so on ).
I do not want use vlan and i read on ml that if i do not setup them,
they are just ignore from CS.
Assuming that i have a public ip class like 1.2.3.0/24.
On public traffic ( system vm i think ) i setup a range like following (
example ):
gw: 1.2.3.1
netmask: 255.255.255.0
start ip: 1.2.3.21
end ip: 12.3.30
On guest traffic ( on vSwitch0 so guest public traffic ) i want setup a
different range but in SAME subnet:
gw: 1.2.3.1
netmask: 255.255.255.0
start ip: 1.2.3.31
end ip: 1.2.3.128
I can not do this cause CS stop me, warning about netmask/gw overlaps.
So i came to 2 possible solution:
1) Do subnetting for network: 1.2.3.0/24 and assign a /29 to public
traffic ( system vm ) and different /28 to guest traffic.
2) Assign to public traffic ( system vm ), private IPs that will be
natted to my router, so i can assign all public IPs that i want to guest
vm. Also here i am not sure if everything works after that.
So my questions are:
1) Why system vm should have internet connection ? They need to receive
incoming connection or i can nat them in order to reduce public ip usage ?
2) There is no other solution ? Can i skip somehow CS warning about
netmask/gw overlap ?
Waiting for your reply
Best regards
