Hi,

I want to achieve following task:
1) Have multiple VLANs (1000+) that are separate from each other
2) Be able to create CTs in those VLANs BUT they are not supposed to talk to each other (cross VLAN) and/or snoop any traffic that is not in their respective VLANs
3) Be able to connect/communicate from one VM to all of those VLANs

Why? I want and VPN server, that will be able to talk to all CTs but CTs are not supposed to talk to anybody except to VPN server on selected VM.

One of my first thought would be to create multiple OVSBridges, then:
1) When creating CT, add it to corresponding OVSBridge
2) Add All OVSBridges to VPN VM

But, according to my previous question, this is not possible due to limit of 32 interfaces in VM:

What would be the best way to achieve this?


Thank you for your support

I did it with FreeBSD by tagging one Virtio NIC with many VLANs. But you can also do it with Linux or even Windows.
