hello folks, i have just switched to linux (ubuntu) and i officially hate bill gates. meanwhile i am trying to setup my web server but xfinity cant recognize the mac!!! please help so i can port forward and do websitey activites

ez way: xampp (no interweb connection) slight hard way: use ethernet (or use netgear as internet)

use a cloudflare tunnel so you dont have to poke holes in your firewall :) heres a tutorial (youtube) but keep in mind you need a domain connected to cloudflare and a relatively modern server (which i highly recommend for security reasons).
orr just raw dog it
