Hi everyone, I'm new to Proxmox and I can't configure my CHR in Proxmox.
I used VMware and configured the CHR to receive a link on Ether1.
On Ether2, I configured it to work with VLANs 10 and 20, for example.
I created DHCP for the VLANs and configured ports and a firewall with the CHR.
Each VLAN was separate, and the virtual machines received their IP addresses through the CHR.
Today I'm trying to do the same procedure in Proxmox, but I'm having trouble. How do I do this? Can anyone help me?

Are your Proxmox interfaces (vmbr0...) configured to be VLAN aware?

Yes, In MiKrotik, I set vmbr0 to receive "internet" and vmbr1 to receive VLANs.

In Proxmox, I configured the networks like this.

auto vmbr0
iface vmbr0 inet static
address 192.168.0.9/24
gateway 192.168.0.1
bridge-ports eno1
bridge-stp off
bridge-fd 0

iface idrac inet manual

auto vmbr1
iface vmbr1 inet manual
bridge-ports none
bridge-stp off
bridge-fd 0
bridge-vlan-aware yes
bridge-vids 2-4094

In the test vm I applied the network interface to vmbr1 and Vlan Tag 13

Hi, you will need to setup using Proxmox bridges and VLAN tagging. Please try this...
  • Create one bridge (e.g. vmbr0) for WAN (CHR ether1).
  • Create another VLAN-aware bridge (e.g. vmbr1) for LAN and VLANs (CHR ether2).
  • Attach VLAN interfaces (10, 20, etc.) to that bridge in CHR and set DHCP per VLAN as before.
Hope this will help you get unstuck.
