I have a Router (Speedport Smart 4) and 3 Mesh Repeater running. All connected over LAN with the Router.
Now i have an OpwnWRT Wifi AP. I want to connect it via LAN to the Router and want to create a guest wifi in this openWRT AP. But this Guest WIFI should have no access to the private LAN devices, only to the internet and if possibla its own DHCP with different IP adresses.
Ist this possible ?
I have my doubt and i am not sure if it possible at all.
Wirless Guest client <-> OpenWRT AP Guest Wifi <-> LAN <-> Speedport Smart 4 <-> Internet
Access Internet but not LAN Devices (like NAS, Smart Home, etc....)
I have a passion for vlans, they solve many problems for me, however your solution also works but only on the openwrt router, it seems to me that having a mesh is the best strategy (and of course high learning curve) they solve the problems later.
