I have a Proxmox 8.3.0 host with two network interfaces:
vmbr0 is the LAN/management interface
vmbr1 is the WAN interface.
On the Proxmox host I've installed opnsense 25.1 with two virtual nics:
vtnet0 is the WAN interface that is connected to vmbr1
vtnet1 is the LAN interface that is connected to vmbr0
opnsense is accessed via 172.16.2.11 on vtnet1
Two issues:
1 - How do I tag the "default" management subnet with a VLAN ID in opnsense? Is it even possible to do? I'd like to be able to handout an IP based on the VLAN id the switchport is tagged with.
2 - After creating a VLAN in opnsense, the interface does not appear in services for me to setup a DHCP range. Only the "LAN" interface is available for DHCP. I think I'm most likely missing a step. I've been able to do this before but completely forgot.
