No. WWB doesn't do anything with Dante. It simply calls from the network. As I sit here typing this, I have 2 ULXD4q's connected to a redundant Dante network via a Yamaha SWP1-8 Switch, RIO and QL5 mixer. All I had to do was connect my computer to the switcher with my LAN set to DHCP. The Dante information is a totally different traffic way and standard network traffic works alongside it.
Now there are a couple ways to set up the ULXD's though. You can set them for DHCP or static. I believe they come set for DHCP and whatever they come from the factory is fine and should talk to WWB without issue. You just need to be sure of your LAN settings. If it doesn't see them when in DHCP then try a Static setting that is in the range of the ULXD's. You can plug into the secondary or primary port and utilize WWB.
