I have on a raspberry pi3 and pi4 both libreelec with kodi (18 on the pi3 and 19 on pi4) and with the docker addon installed on both.
In docker I installed home assistant on both systems.
Both work fine from my own intranet.
On my router which has dd-wrt firmware I created a route to open the homeassistant port and redirect it either to the pi3 or pi4 ip adres.
The problem is now that it works fine for the pi3 but totally not for the pi4.
Something blocks access from the internet to homeassistant on the pi4 and I have no clue what it is.
Anyone an idea?
