Hello! I am new to openWRT. I would like to know if there is any way of mac filtering where I only allow devices starting with, say, 00:0A:BC to connect to the router. While trying to find out my options with Luci, I only found a way to filter by full MAC addresses, and I didn't find any wildcard option or something like that.
I am using OpenWrt 19.07.9 r11405-2a3558b0de in a Mikrotik RB2011UiAS-2HnD-IN
Hostapd is not able to use wildcards for Mac addr access or deny list. You may want to / have to look at free radius.
I recently pushed a merge request to enable vlan assignments for PSK because of the nearly same problem. I wanted to give well known stations a certain vlan and all others another default vlan, and hostapd alone was not able to do so, but radius can fill that gap. Even if you don't want to assign vlan based on the radius config, it can handle to final accept or deny.
