The answer depends on your dhcp server (and not) ;) I think. Did you check in your DHCP server manuals if it supports this type of attribute? What is your DHCP server? By the way, it is usually possible that your pupils might give an IP manually, it is not so secure to trust only to the DHCP server.

So your pupils use wireless cards to connect to the network?
Can you give more details about the hardware and software?

Freeradius has IP pools, you can define a pool and make certain MAC addresses use the IPs from the pool. See Framed-IP-Address attribute(if I am not mistaken, it was something like that) But does your wireless ap/dhcp server etc. support this? that is the question...

Hi All,

My first post so please be gentle :)

We've been having a few problems with pupils joining our LAN using their
own kit. Although we'd like to allow this at some stage (under our rules
obviously) we'd like this to be done in a sensible, secure way.

Now I have set up a FreeRADIUS box on OS X, it has MySQL support and so
far, so good it works fine. If I setup a wireless AP to use it, it works
like a charm. Fine.

I'd like to now setup a scheme for the RADIUS box to match MAC Addresses
to a range of IP addresses (particularly a scope our DHCP server will send
out). I am therefore hoping any pupil laptop in the future will be allowed
access as long as the MAC address is known and they are using a particular
IP range.

Is this doable with FreeRADIUS???  I presently am using dialup_admin to
admin the system and it has a IP Address field in the new user and new
group setup. Can I add a range in the usual 192.168.1.0/24 notation to say
the group and make all Pupil users a member of that group???

Would this work or am I completely barking up the wrong tree.

TIA

Dan
