Add IPv6 network configuration to disable privacy extensions

Feature Requests
#1

When you want to connect to HomeAssistant via IPv6 from the internet, your router must be able to forward the request to HomeAssistant.
This is not working, when IPv6 privacy extensions are enabled.
Please add an option in the network settings, to change this behaviour:
[ipv6]
addr-gen-mode=eui64

#2

Yes, that feature is really needed. I’m fighting with addr-gen-mode since hours!

#3

When I think about it. Home Assistant is a server system and the default ipv6.addr-gen-mode for servers should be eui64. Maybe we don’t need a UI extension and it should be default anyway.

I didn’t get it to work using a USB drive and gave up. Disabled IPv6 completely.

You can change the default settings with:

  • ssh on Port 22222 (see Dev SSH) or
  • The SSH & Web Terminal Addon or
  • with Monitor and Keyboard directly connected to the hardware and run login in the ha-cli

The modify:

vi /etc/NetworkManger/system-connections/

or use nmcli

nmcli c s
# Check that default is used. If not adapt the following command
nmcli c edit Home\ Assistant\ OS\ default

In nmcli run:

set ipv6.addr-gen-mode eui64
safe

If nmcli c s show an second configuration edit this one to.

After these steps. The privacy extension is disabled, but if you use the UI Network settings again, the changes will be overwritten. :frowning:

Thanks for your suggestion, but there is no network manager available in my ha-cli.
nmcli is not installed and the path /etc/NetworkManger is not existing.

I am using homeassistant OS on a Raspi:

| |  | |                          /\           (_)   | |            | |
| |__| | ___  _ __ ___   ___     /  \   ___ ___ _ ___| |_ __ _ _ __ | |_
|  __  |/ _ \| '_ \ _ \ / _ \   / /\ \ / __/ __| / __| __/ _\ | '_ \| __|
| |  | | (_) | | | | | |  __/  / ____ \\__ \__ \ \__ \ || (_| | | | | |_
|_|  |_|\___/|_| |_| |_|\___| /_/    \_\___/___/_|___/\__\__,_|_| |_|\__|

Welcome to the Home Assistant command line.

You need to get OUT of the ha cli, you can run the ha login command, or ssh directly to your supervisor.

For others it may help the exact commands once in the CLI are:

set ipv6.addr-gen-mode eui64
save
quit

This is a solution that works with or without eui64.
