Dears I'm having a problem retrieving the ip of the end user device in the radius.log log file through the% {dhcp_options: DHCP-Your-IP-Address} attribute. Currently my freeradius is in version 3.0.15, using ldap authentication and other default settings. Only the dhcp module was configured to work as dhcp relay as follows: dhcp { listen {                 ipaddr = *                 port = 67                 type = dhcp                 interface = VLAN100         }         #  Packets received on the socket will be processed through one         #  of the following sections, named after the DHCP packet type.         #  See dictionary.dhcp for the packet types.         dhcp DHCP-Discover {                 update config {                         # IP Address of the DHCP server                         DHCP-Relay-To-IP-Address := x.x.x.1                 }                 update request {                         # IP Address of the DHCP relay (ourselves)                         DHCP-Gateway-IP-Address := 127.0.0.1                 }                 ok         }         dhcp DHCP-Request {                 update config {                         # IP Address of the DHCP server                         DHCP-Relay-To-IP-Address := x.x.x.1                 }                 update request {                         DHCP-Gateway-IP-Address := 127.0.0.1                 }                 ok         } } However I get the error message: ERROR: dhcp_options got a ipaddr attribute needed octets. How can I solve this problem. Best Regards, Juliano.
