Hello! I`ve tried to configure my freeradius installation like described here http://wiki.freeradius.org/guide/dhcp-for-static-ip-allocation but it`s very simple case for only one subnet. Now we have two networks which needs to get IP by DHCP server. So is there any possibility to configure DHCP scopes for different networks? Thanks!
Yes. It's not as easy as with a dedicated DHCP server. You'll need to split the packets, so that some use subnet A, and some use subnet B. Look at the packets (radiusd -X) to see how they're different. Usually there will be a gateway IP address different, or perhaps something else. It's probably best to use groups to assign the network parameters. e.g. use the radgroupcheck and radgroupreply tables. For users in group A, assign them options for network A, and users in group B should be assigned options in network B. i.e. separate the *common* configuration into group parameters. Thenm each user should have only user-specific parameters. e.g. an IP address, and a group membership. For v3.1, we're looking at maybe coming up with DHCP-specific queries for SQL. But getting help from other people would be useful, too. Alan DeKok.
