Is it possible to use the reverse proxy in a local network?

[ghost]

I am trying to redirect my local home server IP so that I can access certain services hosted on certain ports using subdirectories.

192.168.1.10:8112
192.168.1.10/deluge

I tried setting my configuration like so but a 404 Not Found page is returned when I try to access the ip/subdirectory:

Not sure if what you are trying to do there is possible, but if your router support it you can have an internal domain name (eg *.at.home) and you can create a host override alias deluge.at.home for your server IP in your DNS resolver and use the same in NPM. So you can use for instance deluge.at.home for 192.168.1.10:8112. I do this for all my self hosted applications.

I think I'm having a similar issue. What do you mean by "router support"? Does it have something to do with this issue:

Also to note, that I'm personally using Synology that has a built in nginx, but I decided to use one in Docker instead. I had to the following mapping instead which I'm not sure if that will effect access.

83:80, 84:81, and 444:443

Lastly I do not have these services opened to the external internet, but will eventually setup openvpn as the only way to access these services.
