I know it is possible to easily setup Client Isolation via LuCi for WIFI clients. However, I could not figure out how to implement it on wired networks.
There are some discussions in this forum, but one of them utilizes a single VLAN for each client, which is not an ideal solution, in my opinion. In another thread the suggestion involves a RADIUS server, which makes things complicated on the client side, too.
How can I isolate clients on wired networks in such way it won't require any changes on the devices' side?
I already have VLANs configured for different groups of devices, and I would like to have some of these VLANs with client isolation.
I'm using OpenWRT 21, if this is relevant.
