I’m trying to host a few docker services from my house, but my IP appears to be blocking port 80, so the only way to get a domain working that I’ve found is domainname.com:portnumber (I have port forwarding set up in my router, and can reach a wide range of ports, but not 80).
It looks like cloudflare will point sites to my IP but not ports, and because I can’t reach port 80, I can’t figure a way to route things through NGINX proxy manager on the same box.
Is there a free external service I can use as a reverse proxy to point requests to specific ports on my self-hosted box? Or else, is there another way to make my sites useable without the enduser having to specify ports?
Since it sounds like this is your home router since you mentioned you use Comcast. If you are testing the site from within your network using your external ip then you are possibly running into a loop back block. Comcast does not allow traffic that originates from within your network back into your network.
Try the ip/site from a Hotspot and that might work.
