Combination of lan_only_cluster and offline_server

[thasmo]

I've tried the following:

lan_only_cluster = false
offline_server = true

What do I expect?
The server is not listed publicly but everybody can join, not only from LAN.

What happens actually?
The server is not listed publicly but it's only possible to join from LAN.

Do I miss something here? I'd love to have a server running in LAN and hide it from the public server list. But I still want people to be able to connect if I give them the IP.

I could set a password for the server, but I just don't want to have it listed publicly, so setting a password doesn't solve this.

Is it a bug? It seems that offline_server does not only hide the server on the public list but it also forces lan_only_cluster to be enabled.
