Linux

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Locally, everything works fine on HTTP (http://192.168.1.222).

Externally, however, only PARTIALLY on HTTPS (https://mydomain:8344) through Caddy. I can connect to the site (first picture), but streams won't start.

Any idea why this is the case? My theory is that the RTSP port (554) is for streaming and that when I go to the local address (that is on 80), the site ITSELF initiates a connection to port 554 in the background. However, this apparently does not happen when I connect remotely.

EDIT: In the same Caddyfile, I reverse proxy my Jellyfin server that only uses a single port, and that works fine. The Caddy server runs on my Ubuntu Server 23 on Raspberry pi 5.

I think you're on the right track here. The DVR is probably telling your browser to connect to http://192.168.1.222:554 for the stream, which on LAN is fine because you have a route to 192.168.1.222, but when connecting externally you won't be able to get to 192.168.1.222.

You can probably check the network connections in dev tools in the browser to confirm that.

Edit: Editing this to also stress the importance of the advice given by @[email protected]. My home cameras are also only accessible from outside my network via wireguard.
