Hi all, I have, what I think is a simple problem, with a simple answer that doesn't work. The environment I am supply authentication requests to, require that I respond with a fixed IP address in each NAS domain. eg NAS-IP-Addresses 192.168.1.0/28 should get an IP from the pool 10.0.0.0/16 While NAS-IP-Addresses 192.168.1.128/28 should get an IP from the 10.1.0.0/16 Users have no control from which of NASs they come into. All the normal user name/password stuff works fine (many thanks!) What I would love to do is set up Huntgroups (OK so that bit works too!) and then in the sqlippool.conf just assign pool-name = %{Huntgroup-Name} This doesn't work, and all I get is pool-name is undefined. Does anyone have any ideas? Kind regards Simon
