Model: ER7212PC  
Hardware Version: V1
Firmware Version: 1.3.1

I have:

 

ER7212PCv1 (with build-in controller)

Firmware: 1.3.1 Build 20250220 Rel.67749

 

EAP225(EU) v4.0 (AC1350)

Firmware: 5.1.11 Build 20250401 Rel. 50587

 

I've setup 3 vlans (1: main, 10: guest and 20: IoT). I've setup 3 wifis as well for each vlan.

My speakers Google Nest Mini are on the IoT vlan20 and my phone are on the Main Vlan1

 

Problem:

I cant find the speaker when I tries to cast from my phone to the google nests.

 

(If I connect my phone to the IoT-wifi/vlan, I have no problem casting to the speakers)

After searching this forum I found, that I needed to setup a mDns rule, wich I did (see screenshot). At the moment at have no ACL-rules.

What else can I do?

 

 

The Bonjour service I've setup manually:

Bonjour service

 

No ACL-rules:

 

Best regards

HiLife

I did. But I mistakenly selected "AP" instead of "Gateway" in the mDNS rule 

 

Now it works.... Thanks

That is good to know.

Usually, if you are using the router as the DHCP server, you want to make sure the mDNS is discoverable from L3. So set it as the gateway.
