Fixed IP

[Guy Davies]

Hi Mahesh,

This is *totally* independent of the authentication process.  You
don't need to do anything to the RADIUS server to do this.

You need a DHCP server.  When your client (the PC) is attached to a
particular subnet, it will request a DHCP address by sending a
broadcast to find a DHCP server.  The DHCP server will see the MAC
address from which the request was sent and, if a one-to-one mapping
between that MAC address and an IP address exists in the config files
for the DHCP server, it will return that IP address.

The RADIUS server's job is over well before that happens (except for
any accounting it may do).

Rgds,

Guy
