I've been trying to troubleshoot this for almost a week and cant seem to figure out what is wrong. I enabled UPNP earlier this year it worked fine but lately I've been getting STRICT NAT warnings from STEAM games.
The UPNP service shows no active connections.
I initially set it up using this guide: https://www.youtube.com/watch?v=g5EJYVnpmlM&t=193s
I've tried reinstalling the UPNP (v 1.7) and miniupnpd (v 2.3.9_1,1)
I've read and tried all of the following:

Did one of the updates break UPNP? Or am I missing something?
My OPNSENSE PC doesn't go through a router but is connected through a network switch.
Try the plugin at 1.8 via 25.7.9.
Will do, thanks!

Still not working.
Here are my UPNP settings (took out IP address).
Windows set to "Private Network" and discovery is turned on. No AV installed. Do I need to configure the Firewall rules?
Here are my firewall and outbound rules.
I don't have "static" checked because I have multiple users playing at a time but if I click static, I can get "Moderate NAT" for most gaming services.
I added port 5353 (differs from the youtube tutorial) but that didn't work either.
Ok, fixed it. Stupid error / typo on IP address... Thanks for the assist @franco!
Hello,
Didn't do anything but happy it works now :)
Cheers,
