Hello, I use freeradius to limit the access to our network by filtering MAC address: XXXXXXXXXXXX Cleartext-Password := "XXXXXXXXXXXX", Machine-Name := "COMPUTER_1" When we receive new computers, we use the FOG software to deploy a clean image on all new computers. The problem is that we have not yet set up Freeradius to allow these news computers to access our network. My question is the following: is it possible to authorize punctually all MAC addresses to access the network while we recover them to configure Freeradius? The idea would be to add a line like : ALL_MAC_ADDRESS Cleartext-Password := "ALL_MAC_ADDRESS", Machine-Name := "NEW_MACHINE" Does Freeradius allow regular expressions in its configuration file? If yes, what should be the form of this regular expression? Thank you in advance for your help. Pascal
