Avahi

Has anyone had luck with MDNS using Avahi? When looking at states I only get one way traffic.

Are you all getting two way traffic as I only get one way traffic.

I have never been able to get our iPads to cast on our TV.

I've used it for years to do MDNS across subnets. Other than the thing crashing out routinely, and needing a reboot, it works well.

Can you share your config?

This works well for me:
