Right, I also set mDNS for all the VLANS

@Tescophil I am not clear about your second to last paragraph... By default subnet for the management lan, you mean 192.168.0.1? It's not already like this by default?

I, finally, successfully, switched my controller to VLAN 10. This was fun, not! My controller is on my NAS as a container, which is now 192.168.10.2 What I had to do was, as suggested, move one PC to...

Well, tried that yesterday and I had to move my server back to LAN for the devices to be connected. Using the discovery tool, I had once seen all the devices in it but had no idea of what to do next....

Ok, tried it and does not work unless I set a DNS server. By then, setting the domain name on Omada does not provide an advantage. Or am I missing something?

So, if I understand correctly: I set the domain for both LAN and VLAN10 to lan[dot]example[dot]com Then from PC1 I can refer to PC2 using PC2[dot]lan[dot]example[dot]com ? No need for a DNS server?
