According to https://docs.opnsense.org/manual/how-tos/multicast-dns.html (https://docs.opnsense.org/manual/how-tos/multicast-dns.html), I should be able to install the os-mdns-repeater plugin by just finding the plugin in the list.
However, my plugin list doesn't include os-mdns-repeater.
I'm on the commercial mirror (with a business subscription)... is os-mdns-repeater only a community plugin, and not available for business?
Also can't find the udprelay plugin.
It's available in the business version, too
