@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.

@jimp Thank you! It worked.
