Proxify iframes panels streams

When adding “iframes panels”, the “final” device must be able to connect directly to the service. Is it possible that Home Assistant is making the requests instead of the client? In my case (HA in docker mode), I would like to expose services via iframes panels but without exposing them to the internet somehow. In the idea, I just create internal private networks between my HA container and my other services, and it is HA which executes the web requests. Unfortunately, after several searches, I couldn’t find the solution.

In my case, I want to make the “vscode” container accessible only from the “hass2vscode” internal network. So the source IP should be the “hass” container.

Thank you in advance,

Hi! Have you managed to proxy requests to iframe through home assistant?
