Proxmox setup with Multiple VLAN DHCP VM Centos 7 server and Cisco switch

[surbanoski.aleksandar]

Hi people,

I am trying to configure proxmox in a way I am able to use DHCP server virtual machine with multiple VLANs. I tried to enable on vmbr0 vlan support :

iface vmbr0 inet static
address 192.168.1.156/24
gateway 192.168.1.1
bridge-ports enp2s0f1
bridge-stp off
bridge-fd 0
bridge-vlan-aware yes
bridge-vids 1-4094

On VM network device I have not defined VLAN in order to receive all VLAN frames


On Cisco switch I have configured Trunk

I don't know if I am going on right direction. One of my other ideas is to attach another network physical interface directly to DHCP server VM and connect to switch trunk port

Thank you very much in advance

your first solution should work,with your vlan-aware bridge without define vlan on proxmox.
(so all vlans wil be see inside your vms, but you need to created tagged interfaces inside your vm for each vlan + 1 ip for each vlan for your dhcp server)
