[PVE-User] Multiple bridge on single physical interface

[Jean-mathieu CHANTREIN]

Hello. 

I try to make this: 

(1) 
<physical_interface0>-----<vmbr0>-----<subnetwork1> 
| 
|--------------------<vmbr1>-----<subnetwork2> 

But apparently, one physical interface can't have 2 virtual bridge. So I try this: 

(2) 
<physical_interface0>-----<vmbr0>-----<subnetwork1> 
| 
<virtual_interface_on_physical_interface0>--------------------<vmbr1>-----<subnetwork2> 

But my virtual interface is not recognize, because I have to fixe an ip address to the virtual interface and I don't want make this trick. 

Globally, I want to make this: 

|-----<host1> 
| |-----<physical_interface0>-----<vmbr0>-----<subnetwork1> 
| | 
| |--------------------<vmbr1>-----<subnetwork2> 
| 
|-----<host2> 
| |-----<physical_interface0>-----<vmbr0>-----<subnetwork1> 
| | 
| |--------------------<vmbr1>-----<subnetwork2> 
| 
|-----<host...> 
... 


VM in subnetwork1(resp.2) on host1 must be communicate with VM in subnetwork1(resp.2) on host2 via just one single interface and my host must be not reacheable by subnetwork. 

How I can make this ? 

I tryed to address my virtual_interface or enable proxy_arp on the physical interface but without success... 

If you have any idea... 

Best regards.
