howto needed for restrict access by MAC over whole WDS

by Dennisfreud / March 16, 2014 10:17 AM PDT

I am between a rock and a hard place here. Managing a holiday resort in Spain I want to offer free wifi to my clients and my clients only. There are also private owners and other guests in the house who are using up my bandwith (very limited due to remote location). A conventional password always spreads fast. So I think the only way to lock unwanted users out is to use MAC access restriction in "allow only" mode. Since my clients stay long term the administrative overhead is acceptable.

But how?
1.) most routers I know allow only some 30-ish MAC allow entries. Thats too little for me. I would need 100, would like 200.
2.) How do I set it up? I have a modem router (at present a TP-Link), a wrt54gl connected by wire to modem as repeater bridge and a second wrt54gl as repeater using the wireless signal of the first linksys as source.

Is there any way to solve my proble without using MAC restriction?
If I do need to use MAC restriction, what router can do what I need?
How do I set up the bridges - or do I need to enter all permitted MACs in all devices?

Or is it really no way to do this without a radius server (trying to get that to work almost drove me crazy).

Any comments or advice very welcome and if anyone ever comes to sunny Tenerife Island, gimme a shout.

Until you change hardware to support that.

I suggest you use the old fashioned change the password monthly or weekly. If folk complain then tell them it's for security reasons.

Administrative overhead to inform all users all the time is too great and, as mentioned, they dont keep it secret.

Then you'll need new routers and access points.

As you revealed above, the paltry MAC count alone means we can't use these routers and WAPs.

And before you go down the MAC road, you are aware I can spoof that? That is, it's not good enough for those in the know.

To keep using your gear you have to consider software like

Dear Proffitt, I have looked into hotspot software but they all seem to have the same flaw, the login data (even though now every user gets his own) is not bound to the machine so users can still share an account. And spoofing is not a problem, my clients in general are not "in the know" that far.

Mind you, I am aware thet with hotspot software simultaneous access with one set of credentials is not possible, but one after the other, for all I know, no problem.

Then how to solve it?

It appears you know enough that you know the current routers are inadequate and you have tried all the hotspot lease systems. What's next is Cisco or such gear that has bigger MAC tables.
