that indeed fixed it, thank you very much! just if you have a little bit of free time, can you quickly explain why upon restarting mt-daapd, iTunes first saw it but then lost it a bit later? I mean … if the firewall blocks things, then it should block it right away and always, shouldn’t it? so iTunes should never have been able to see it …
i’m a bit mixed up by that. anyway. thank you.
When it starts, it sends out a multicast to “pre-cache” the mdns resolvers on locally connected networks. So probably that was going out (permissive firewall — allows all outbound, stops unsolicited inbound). But it has an associated TTL. So after that TTL (somewhere around a half hour), machines tart querying the network for the device. But it doesn’t see the queries (firewall), so it doesn’t respond, so it gets dropped off the browse lists.
So “shows up when starting, drops off after about a half hour” is textbook for not seeing mDNS requests.
