I have a very weird problem:
I have created a vlan300 network.
In this network i can’t connect my iphone with denon HEOS streaming speakers. They are seen by the HEOS app, but i can’t play internetradio over the speakers.
I have created another vlan900 network, and tried this out: same problem.
If i use the default network vlan1, everything works perfectly…
The setup of the network:
Ubiquiti Edgerouter 4 with NO firewall rulles of any kind.
EX2052P cambium switch (4.2.1-r5)
2 x XV2-2(22.214.171.124-r3)
What can be wrong here?
