A new Flyspray task has been opened.  Details are below.

Summary - mdns not received by wireless clients when using dynamic vlans (802.1x)
Task Type - Bug Report
Category - Base system
Status - Unconfirmed
Assigned To - 
Operating System - All
Severity - Medium
Priority - Very Low
Reported Version - All
Due in Version - Undecided
Due Date - Undecided
Details - When using wireless networks with radius assigned dynamic vlans the mdns messages are not received by wireless clients.
mdns messages are correctly sniffed on the wlan vlan, but they seem to never reach the devices.

Using radius with vlan assignement in the "option network" works without problems.

Happy to provide logs or captures as needed.
