Comment on Need help with port forwarding and Cloudflare DNS records

DNS doesn’t deal with ports, it resolves hostnames and that’s it.

What you probably need is some kind of reverse proxy that sits outside of your network, listens on port 443 and then directs it to your home IP address on port 12400.

The first sentence is not really true though.

  If you really want to get anal about it, yes I know there things like CNAME, PTR and MX records too but that’s outside of the scope of this discussion.
  
  DNS doesn’t deal with ports, there’s no way to say: homelab.example.com should point to IP address 1.2.3.4 and port 12400.

    DNS can deal with ports.
    
    You can use a SRV record to specify the port for applications (not browsers) that support it.

    For the discussions regarding OPs web server they want externally accessible, no DNS does not do ports.
    
    For other applications there are SRV records, but that’s beyond the scope of the original question. It sounds like u/spacecadet didn’t want to confuse OP, and while SRV can assist certain applications with ports, pointing it out here isnt helpful.

I’d say Nginx Proxy Manager is the easiest reverse proxy I’ve used.

  Sure, but the point is not so much about which one to use but that the terminating point listening on 443 should sit outside of his network.
  
  So he will either need a cloud service, or accept that he will have to add :12400 to his URLs.
