Transferring tagged traffic to a virtual machine, how?

Question

Computer networks

Good day! I want to transfer tagged traffic to a virtual machine that runs in proxmox. But I don’t know how to properly configure the network on the server where proxmox is running?

Answer 1

1. There is a physical port in the eth0 system that receives tagged traffic
2. Create a kvmbr0 bridge, including the given eth0 interface there
3. Create a vlan on kvmbr0. For example VLAN=100, i.e. kvmbr0.100
4. Create a vlan100 bridge and include kvmbr0.100 there
5. Bridge the Proxmox virtual machine with this vlan100 bridge
=> According to the idea, you should receive tagged traffic on the Proxmox VM

Answer 2

in proxmox you can create an interface with a label, this label is a tag for vlan, you send traffic to the incoming interfaces of the hypervisor in the vlan with the corresponding label
