Hi, if anyone is interested in customizing the source code for me, please check out either site: http://www.getacoder.com/projects/c_developer_radius_expe_102912.html http://www.odesk.com/jobs/Developer-with-RADIUS-Experience_~~f48a82c177d7e1b 3?tot=129&pos=7 I would like FreeRADIUS to check incoming requests based upon the domain (derived from the username), instead of the NAS IP addresses. Thanks! Eric
