iptables rules from freeradius...

[tbsky at annsky.us]

Hi:
   i am using freeradius as wireless authenticator.
   windows xp client is using wpa + peap.
   and authentication through wireless ap is ok.

   now i want to setup some iptables rules for authenticated users.
   i wonder if this can be done via freeradius.
   can i find out the mac address or ip address information for
   authenticated users?  can i run iptables scripts when a user
   authenticated successfully ? since ip address is offered by dhcp
   server after authenticated, i think it's difficult to get this info
   from freeradius. maybe there are better ways to implement what i want?

   thanks for reply !!!

Best Regards,
