Does anyone know if it is possible to implement something like this on the omada gateway:
Clients should connect to the network by default without internet access (both wired and wireless)
Individual clients are registered manually, who need internet access.
I did not see such functionality on the ER7212PC

Is that what you want? Portal?

But cannot do the second request you want. They will either automatically authenticate with the portal/auth server, or you simply allow them to connect and then remove unwanted users.

They cannot be held in a status like "pending for your action on allow or deny".
