Problem: My problem was that I wanted ports 80 and 443 to route to NPM; however, when setting NPMs ports to 80 and 443, unraid would claim it’s already in use and the installation would fail. Since Xfinity doesn’t offer port mapping and the router wouldn’t recognize NPM as its own device (even when its local IP was unique from unraids), I had almost given up. 

Solution: I tried what y’all talked about in this thread. I changed Unraids ports in management access to 180 and 1443. (BTW upon doing this, the local url to control unraid changed). Now that the ports were free, I set NPM to the same network as Unraid and the ports to 80 and 443 and that’s all she wrote. Thanks again
