How to allow Omni to communicate with Talos with host firewall enabled

[tz-torchai]

Hi,

How to configure host firewall so Omni can talk to managed Talos nodes? I tried enabling host firewall (hostFirewall.enabled=true) and all nodes became offline.

You may be better off using Talos's host firewall, instead of Ciliums https://docs.siderolabs.com/talos/v1.12/networking/ingress-firewall#ingress-firewall Otherwise you will need to explicitly allow the Talos and Omni control ports.
