I own a Brume MV1000 (no wireless) and I am using it in full router NAT mode.
I want to only allow certain devices on my LAN to have access to the network. I appreciate that MAC address filtering is imperfect and easily hacked, but it is a good start until I have time to implement freeradius or something like wireguard.
So I need a way to easily add an allow list of MAC addresses and deny all others.
I have found this in the OpenWRT wiki but it assumes you have a wireless router
which I do not (the advanced GUI does NOT have the wireless menu with MAC address filter tab)
So it looks like I am left with using firewall traffic rules which is more complicated to implement
Has anyone achieved this and if so what is the best way to do this without messing up my current default firewall traffic rules?
