Multiple Home Assistant platforms with Duck DNS on one home wifi network

Tags: #<Tag:0x00007f32746c5ab8>

Hey Everybody,

I have three Home Assistant systems installed onto three different Raspberry Pi 3 B+'s. I am struggling to figure out how to port forward multiple IP addresses for one port on the same router (currently, my router will only allow one IP address for one port). The port forwarding I am presently using is 443 -> 8123.

The link below leads to a video I used to set up Duck DNS on HA.

P.S. I know it is weird to have three Home Assistant setups, but I need them for a research project I am participating.

Any help will be appreciated because I have been trying to figure this problem for some time now.

Thanks,

Sam

Use this guide :

Then forward 443 to your nginx. I have 3 HA’s too :slight_smile:
