I'm using it exactly for this sort of thing (I needed to forward mDNS
zeroconf stuff across VLANs, to allow fruit-branded laptops and
smartphones to use printers, and stream audio to hosts running
shairport-sync + sndio, whilst keeping them all segregated on their own
VLANs).

Pretty straightforward to configure. It's all done in
/etc/avahi/avahi-daemon.conf, but let me know if you need a hand.
