Wi-Fi Access using MAC filtering

[NitinPowar99674]

Hi Experts,

I want to use MAC filtering to access the wireless network. But I don't have a RADIUS server.

Most of the devices are IoT based

So, please guide me on this matter.

In this case, I will be installing MR76

Don't see how you'd achieve this without a NAC/Radius server? You could look at doing this with IPSK with Radius using Freeradius (open source).

As mentioned, RADIUS is needed for that. But as MAC-filtering will not add any security benefit, I would go for "Identity PSK without RADIUS" to give different groups of IoT devices different PSKs and group-policies.

Thanks for your reply.

I want to give some details of my ongoing deployment.

We use one subnet for all wired and wireless networks so all users including IoT are in one subnet.

All IoT devices use only a wireless network and other users connected on the wire.

So please advise, how can I implement these policies?

Would still go for "Identity PSK without RADIUS".

@NitinPowar99674 that isn't great from a security point of view IoT devices are notoriously (insert favourite expletive) in terms of updates and general security so I'd look to change to a different setup where you use VLANs and can secure IoT devices off from the rest of the network.

@NitinPowar99674 Meraki doesn't support the use of MAC filtering without using Radius. Radius is a requirement, if you don't have a radius server your options are set one up or choose a different authentication method.
