@Khun_A-Than88 all access points must be adopted on the same site.

@Geoslay Do you have ACLs, isolated networks, or other things that can block between VLANs ?

@Collinfranco firstly, you should not use port forward to wireguard on the router, it will just be a mess. secondly, you can't check if the port is open to a UDP port. it will show closed even if it...

@PP_ it looks right so I don't know, maybe the Omada team will have to look into it

@PP_ here is a little test I did and pinged from vlan1

@PP_ do you have a screenshot of the lan configuration on vlan3
