What ports does home assistant use? Debugging renamed network interface

Hi,

Since 0.114 I am having the issue that every other day my rpi 4 looses its network connection.

The issue seems to be this line in /var/log/messages

Oct  3 03:12:53 raspberrypi kernel: [32566.539759] eth0: renamed from veth3cfa92a  
Oct  3 03:12:53 raspberrypi kernel: [32566.608483] IPv6: ADDRCONF(NETDEV_CHANGE)

It appears that something renames the network connection, which of course wreaks havoc wrt the connection.

I am running HA in a docker container with network mode: host and I’d like to see if not running it in host mode solves the problem, i e of this problem really comes from HA.

Which ports should I forward if I want to keep most functionality. I know I’ll lose mdns, but that’s OK for the time being.

Thank you for your help.
