While i appreciate the detailed response here i did make another comment letting OP know i'm in a similiar situation as them, i use Docker Engine & Docker Compose for my self-hosting needs on a 13th Gen Asus Nuc (i7 model) running Proxmox with a Debian 12 VM. My reverse proxy is traefik and i am able to receive SSL certificates on port :80/:443 (also have Fail2Ban setup) however, i can't for the life of me figure out how to expose my containers to the internet.

On my iPhone over LTE/5G trying my domain leads to an "NSURLErrorDomain" and my research of this error doesn't give me much clarity.

This is a snippet of my docker-compose.yml

services:
  homepage:

Image of my port-forwarding rules (note; the 3000 internal/external port was me "testing")

**Edit:** I should note the [Asus Documentation for Port-forwarding](https://www.asus.com/support/faq/1037906/) mentions this:

> 2. Port Forwarding only works within the internal network/intranet(LAN) but cannot be accessed from Internet(WAN).

>  (1) First, make sure that Port Forwarding function is set up properly. You can try not to fill in the  [ Internal Port ] and [ Source IP ], please refer to the Step 3.

>  (2) Please check that the device you need to port forward on the LAN has opened the port. 
       For example, if you want to set up a HTTP server for a device (PC) on your LAN, make sure you have opened HTTP port 80 on that device.

>  (3) Please note that if the router is using a private WAN IP address (such as connected behind another router/switch/modem with built-in router/Wi-Fi feature), could potentially place the router under a multi-layer NAT network. Port Forwarding will not function properly under such environment.

> Private IPv4 network ranges:

> Class A: 10.0.0.0 – 10.255.255.255

> Class B: 172.16.0.0 – 172.31.255.255

> Class C: 192.168.0.0 – 192.168.255.255

> CGNAT IP network ranges:

> The allocated address block is 100.64.0.0/10, i.e. IP addresses from 100.64.0.0 to 100.127.255.255.

I want to highlight the fact that i may be under a multi-layered NAT, the folks in my household demand the ISP router given that i have PiHole running DNS blocking and my Asus Router routes all outbound connections through a VPN tunnel, besides DDNS obviously which my router also handles, i have to run these routers in bridged-mode so that they share the same WAN IP **but**, if I am able to receive SSL/TLS certificates from LetsEncrypt on port :80/:443 that means port-forwarding is working as intended right?
