I see nothing.
What I see is blocked packages in the firewall:

It is this port:

mdns 5353/tcp # Multicast DNS


Should I open it? [...] Indeed, after I open it I see a few things in "avahi-discover-standalone". The printer twice (ipv6), and my computer, three times (ipv4, workstation, sftp, ssh). My laptop, the DTV and the router, do not appear.

It lists open ports as one entry per machine, it seems.
