hi alan, first of all thanks for your feedback! now i'm going to explain better: i'm in WiMax context with freeradius 2.1.1 and i want to differentiate several clients to assign addresses according with realm; here's an example: i've client1@realm1, client2@realm1 and client3@realm1 and there's also client4@realm2. now i'd love that my dhcp assigns IPs from 10.x.x.x pool to the realm1's clients and IPs from 20.x.x.x pool to the realm2's client.
Ah. That's a very good use-case.
so do you know if it's possible to do with classic dhcp server [dhcpd]?
No. It's pretty much impossible.
or with freeradius's embedded dhcp server? or i'm guessing something impossible?
It's possible, but it requires some code changes. The server can send and receive DHCP packets. It can allocate IPs from SQL for RADIUS queries. But it can't yet allocate IPs from SQL for DHCP packets. What you *can* do is allocate IPs when the user logs in. The NAS will ignore the IP address in the Access-Accept, but the IP will still be in the SQL database. Then, when the DHCP packet comes in, SELECT the IP based on the MAC address, and return it to the user. This should actually work in the current server... Alan DeKok.
