NGINX as a reverse proxy on OPNSense (multidomain mode with single public ip) ?

[spravce_eko]

I use NGINX as a reverse proxy (offload ssl), now it is located behind
OPNSense. It's in multidomain mode with single public ip.

HTTPS port on public ip I would need non-standard ports eg 8443 etc.

Is it possible to use NGINX directly on OPNSense in the same way?
I followed the instructions at docs.opnsense.org, unfortunately without success.

Has anyone run it the same way? Is it possible to give an example configuration?

Can anyone assist in troubleshooting Unbound service not starting.
Can Unbound be uninstalled and reinstalled?
