Hello, In my network there is Cisco ISG acting as DHCP relay. It relays requests from customers to DHCP server of freeradius:

The dhcp configuration is default from raddb/sites-available, I only added 'detail' in every dhcp-section. Any ideas? Thanks in advance. -- MINO-RIPE - List info/subscribe/unsubscribe?
