Multicast mDNS

Hello is it possible to route that multicast to another interface

at the moment we are using this for apple mobile printing. so the mobile print server is on Port4  and the WLAN iPhones on Port6 (WLAN)

other information:

PrintServer (LAN Port4)

WLAN Device: (WLAN Port6, PoE Switch connected the Sophos AP55C)

I try to establish the communication between the wlan devices and the print server for air print.



any ideas?
