Hi
I have a fresh install of Proxmox 7.1.

I have two ubuntu 20.04 server install running and one of them get ip from vlan 30, when i try to spinup the next vm i dont get any ip adress from the same vlan, if i change vlan tag to non i get an ip from the untagged network.

I also have TrueNas running on vlan 30 and no problem to geting ip.

I have one vm on vlan 20 and it wont get any ip.

Some ide of the problem?
 
Depends on how you are handling dhcp on your network. You will generally need a DHCP relay or IP Helper address on your router to allow requests to be assigned to the correct vlan scope
 
I have DHCP for every vlan setup on my router and also have a early Proxmox setup running version 6.3 (on server 1) and if i try the different VLAN tags with my Windows 10 VM in that machine i get ip from vlan 20 and 30 but not on the new Proxmox server (server 2) running version 7.1
