Hello,since I've received no answer yet - I tried many configurations on my own.By now I have installed mdns responder and started it for interfaces LAN, VLAN100 and VLAN101.((Shall I start it everytime we restart the appliance??))I built up an interface group for LAN, VLAN100 and VLAN100.And I setup an any-any rule in every interface to test.At mdns I see the broadcasts from clients and printers get repeated rightly.I'm sure only a few steps away from solution.Can you provide me with screenshots of your rule-set or shall I post mine?ThanksLukas
