Airplay doesnt work on new network

Weird problem. We just got new Verizon Fios Gigabit router an airplay doesn’t work on the Vero 4k.

Boots up just fine, I can play everything, i can see the network, internet. I can SSH to it.

When i switch back to the old fios router, the airplay works.

Thoughts ?

It might be that multicast bridging isn’t working (or isn’t currently configured) on the new router. This post provides a bit of background and an iperf3 test you can try:
