Config file questions

[jcdick1]

I was following the tutorial for getting Caddy up and running, but at one point, the writer mentions adding a line to the /etc/rc.conf file.  I'm not sure about the previous version, but my recently updated 19.7 install doesn't have this file.  Where would that be?

Also, if I'm running a reverse proxy directly on my OPNsense box, what would the firewall rules for 80 and 443 look like?  I've done port forwarding to other hosts, but never opened a port for my router itself.  Localhost?  The LAN IP?

Any guidance is appreciated.
