 Once everything is ready, I can apply the SDN configuration. In `Datacenter` > `SDN`, I click on the `Apply` button, after a few seconds, the new zones appear:

 In a old VM which I don't use anymore, I replace the current `vmbr0` with VLAN tag 66 to my new VNet `vlan66`:

 After starting it, the VM gets an IP from the DHCP on OPNsense on that VLAN, which sounds good. I also try to ping another machine and it works:

+## Update Cloud-Init Template and Terraform
+
+To go further, I update the bridge used in my cloud-init template, which I detailed the creation in that [post]({{< ref "post/1-proxmox-cloud-init-vm-template" >}}). Pretty much the same thing I've done with the VM, I replace the current `vmbr0` with VLAN tag 66 with my new VNet `vlan66`.
+
+I also update the Terrafom code to take this change into account:

+
+I quicky check if I don't have regression and can still deploy a VM with Terraform:
+```bash
+terraform apply -var 'vm_name=vm-test-vnet'
+```
