UPNP via OpenVPN

577/5000
Hello everyone,
I have a VPN connecting my home to my business.
from home I would like to be able to visualize the machine of the company via the discovery network microsoft.

Network Info:

Lan company: 192.168.1.0/24
Lan Home: 192.168.2.0/24
Open VPN: 192.168.3.0/24
opnvpn in tun mode, peer to peer

I installed the os-upnp plugin on 2 opnsense, enabled.
But it still does not work.

Is there anything else to do?

The rule is any any through the VPN

Upnp configuration:
external interface = Wan livebox
LAN interface: LAN, VPN
Allow UPnP Port Mapping enabled

UPnP relies on multicast for discovery. You may need a tap OpenVPN device instead of a tun.

Setting the topology "subnet" may also work: https://community.openvpn.net/openvpn/wiki/Topology
