Hello, I'm having an issue with getting Upnp running. I looked up and triple check many tutorials on how to install and start it, but the service will not start. I reinstalled Opnsense on my machine twice already thinking something might have been corrupted during install, but that did not work. I am not sure what is going on.
I've never used Upnp on Opnsense, but have had similar issues with other services. It's possible there's a tcp/udp port conflict, so try that. If you can't change the port it listens on, you may need to change the port of the conflicting service.
I fixed the issue. I found out after digging in the routing logs that it did not like me using what was considered a public IP address. I changed my LAN IP address to the 10.X.X.X group and it fixed the issue.
I recently switched from Pfsense and it allowed me to use 9.4.5.X as a LAN IP address. My knowledge of pfsense or networking is very limited in general. I just learned what I could from videos and such. I have no formal technical training so I was super stumped as to what was wrong.
