Change NPM Listen port based on Proxy Host

[CrazyVaclav]

Hi, I have two proxy hosts in my NPM docker container: I.) Public Website and therefore Port 80 and 443 should be used for NPM to listen on and forward to port 80 of the target HTTP Joomla app. I want that this app is accessible with port 80 and 443 II.) Private self build web app that only I will access. I want that this second proxy host is ONLY accessible via Port 8443

In my docker compose file I created a Host:Container Mapping for all three ports:

    ports:
      # These ports are in format <host-port>:<container-port>
      - '80:80' # Public HTTP Port
      - '443:443' # Public HTTPS Port
      - '8443:8443' # Private HTTPS Port
      - '81:81' # Admin Web Port

What I can do so far is add listen 8443 ssl http2; to the Advanced Tab in the target proxy host number II

That opens up Port 8443 for the proxy host number I and II. and Port 443 is still open for proxy host number I and II.

Is there a way to change the default 443/80 listen ports of NPM ONLY for proxy host number II ?

I have exactly the same issue, its possible to remove 80/443 in the XX.conf file manual. then just change a different config to restart nginx, but will be added from ui again after some changes on the host config. so its not really a persistent solution.

it would be really nice to have the option to comment out the default listening in a config by a checkbox/switch, to be able to listen only on custom ports inside the advanced config and not the default 80/443 set.

So i found meanwhile a workaround to make it persistent. Iadded an additional mount point for the /app/template Folder

-data/docker/local/npm/letsencrypt:/etc/letsencrypt
- /data/docker/local/npm/templates:/app/templates

Then added the content Manual from here: https://github.com/NginxProxyManager/nginx-proxy-manager/tree/develop/backend/templates

then change the template _listen.conf added # everywhere to not listen on anything in any case.

listen 11111;  # << Random not mapped port 
{% if ipv6 -%} 
#listen [::]:80; 
{% else -%} 
#listen [::]:80; 
{% endif %} 
{% if certificate -%} 
#listen 443 ssl{% if http2_support %} http2{% endif %}; 
{% if ipv6 -%} 
#listen [::]:443 ssl{% if http2_support %} http2{% endif %}; 
{% else -%} 
#listen [::]:443; 
{% endif %} 
{% endif %} 
server_name {{ domain_names | join: " " }}; 

now in every new confing the default listen will be commented out, and you have to manually add it in the advanced config.

listen 80; 
listen 443 ssl http2;

or in you case:

listen 8443 ssl;

this makes the http2 and SSL switches in the UI kinda useless and is more Work but its Persistent.

I'm trying to make the custom listening port work with WebSockets but the default toggle in the UI does not work. Any idea what I need to add to the advanced configuration?

Alright, I don't want to revive a dead post, but I tried this and it worked. Sort of, it forwarded it to my port, but it's not ssl secured?
