Can you change the wireless MAC address of a SG-2440 Security Appliance?
-
Hi there!!
I'm interested in buying the SG-2440 pfSense Security Gateway Appliance (https://store.pfsense.org/SG2440)
Is it possible to change the MAC address of the wireless card and the system's hostname?
Please, I want answers only from people that have done it, I want to be sure before buying it.
Many many thanks.

Uh. You can change both on ANY box with pfSense installed.

When changing the MAC address, its always worth making sure your changed mac id is still on the list otherwise made up mac id's will stand out like a sore thumb. This way any bad actors will attempt to use known bugs/backdoors which might not work on your changed mac id.

I asked in case it had any restriction or the wireless card has something else weird that prevents you from changing the MAC.
yeah, that's odd but I had to be sure :PA friend of mine told me that the wireless card might be incompatible and i won't be able to change the MAC.

Thanks for the tip, i'll keep it in my mind.

You can, of course, change the MAC if you want. Regardless of hardware.

::) I'll note that "firewalluser" is our resident conspiracy theorist. This is probably not useful in any way, shape or form. Changing the MAC in general probably isn't all that useful. But if it makes you feel better, knock yourself out. If you're going to change it, might as well change it to some other vendor ID I guess. Pick one that's actually used for wireless if you feel you must.

Pretty much. I only change MAC when
- it's easier and faster than calling $random stupid ISP to let them know I changed my HW so that they let me in
- I know it will prevent getting a dynamic public IP changed (or, to actually force the change).

Without all the data how can you form a judgement?

Is it a judgement or an opinion?
:o

The only situation where I've ever heard of MAC spoofing being a problem is on a minority of the crap Realtek 8139 100 Mb NICs. Even then it works, but you have to keep the NIC in promiscuous mode all the time for it to function with a MAC other than its own. The NICs we sell, wired or wireless, certainly won't have any such issues.

It's really far-fetched to think there are wifi exploits out there so awesome they can own you through the air (a type of vulnerability that's proven very rare to date), but so lame they're foiled by changing your MAC address.
