@tman222 It sure does - helps a lot. Yes, I have a dedicated management PC with the Unifi Controller installed. I will be sure to set up Port 4 correctly. Cheers!

@kom The first link I glanced over before but I can now access the web server both on the WAN and LAN. I'm even able to ssh to it from LAN to OPT1. I don't remember if it was one of the videos you linked or some random third video but I didn't understand that request get sent out on a random port. So those source ports would have never worked. Sorry for not understanding that sooner. Thank you for the references and your time.

@johnpoz When I installed pfSense on the new router I created two interfaces... I had read on the basic firewall page that OPT interfaces have no rules and forgot that - thanks for setting me straight and waking me up. Firewall rules are scary but I'm getting there.
