option 82 config help

[Bill Shirley]

Just a thought (untested):
subnet 192.168.6.0 netmask 255.255.255.0 {
.
.
     pool {
         set special82 = "yes";
         allow members of "something";
         deny dynamic bootp clients;
         range 192.168.6.64    192.168.6.95;
     }
     pool {
         set special82 = "no";
     deny members of "something";
         deny dynamic bootp clients;
         range 192.168.6.64    192.168.6.95;
     }
}
.
.
if special82 = "yes" {
     log ( info,
         "blah blah your stuff here"
     );
}

Hope this helps,
Bill
