MAC Whitelist

Hi,

I didn't find it in the Knowledge base, so here is a guide how it should work out.
Please note that you must pay attention to how you have set up your wireless network. Bridged access points to the LAN or other configuration settings could cause problems and you may need to adjust these other settings accordingly.

1. Add a so called Mac host at System > Hosts and Services > MAC host
   
2. Add a firewall rule to allow traffic from Wifi Zone and the specific mac host list to WAN
   
3. Don't forget to create a SNAT rule to masquerade traffic when going out to WAN
   

Kind regards,

Another approach is to use the MAC Filter in Wireless.

This would allow / deny a Client connecting to the wireless. 

Haha that's true, of course. Unfortunately I haven't had anything to do with wireless so far because I run my private lab on a vSphere environment. Thanks for the hint :D

So, LuCar Toni is there a situation when using firewall rules with WiFi as zone is required?

Ahhhh perfect, thanks a lot!

SSID Macfilter will prevent the Client in connecting to the AP in the first place.

MAC Filtering in the firewall will basically stop the packet on the Arrival and do not process the packet any further. 

Okay, easy and clear to understand! :)

So last point now in this conversation, wondering how best to combat Mac spoofing in the area of wireless protection... Are these articles the right way or do I have to consider something different regarding protecting my wireless network against it?

Cheers,

MAC Spoofing is some sort of difficult in those approaches. 

First of all, you would go with a Encrypted Wireless. WPA2 Enterprise would be a good way to go, if you have concerns about MAC spoofing. 

This will increase the entry level for a attacker.

The Whitelist approach is the next level for an attacker. He has to find out a whitelisted MAC address. 

Those two approaches are the first level on Wireless level.

Next could be, to activate a detection system like MAC spoofing on XG.
