<![CDATA[Howto MAC-Filter with RED+GREEN]]>Hello everyone,

I use the first time pfSense and I want to protect our WLAN Netzwork.
Unfortunately my pfSense-Server has two NIC´s only. So I could only choose RED and GREEN Network.
The RED Interface is our UMTS-Router and the GREEN Interface our safe (WLAN Accesspoints only) Network with some Notebooks and Smartphones.

Our Network:
INTERNET–----UMTS-ROUTER--------pfSense------SWITCH--------5-WLAN-ACCESSPOINTS ------------ MANY CLIENTS

How can I lock unauthorized Computers for example with MAC-Filter in pfSense?

Take a look under Services–>DHCP Server.
--> "Deny unknown clients"
--> "Static ARP"
--> "DHCP Static Mappings for this Interface"
