Hello everybody I change the version of Freeradius (2.2.4 -> 3.0.4) beacause I have a problem when I used the DHCP relay feature. When I used the freeradius version 2.2.4, my DHCP relay send DHCP-Request from x.x.x.x:20675o y.y.y.y:67 but the reply packet is y.y.y.y:67 to x.x.x.x:67 On the Bug fixes list , I see the problem was solved using Freeradius 3.0.4 (http://freeradius.org/version3.html, Use correct port when DHCP relaying, ) So I reinstall the Freeradius 3.0.4 on my server but the problem is still present and my server dropped the packets. 17:42:23.875867 IP 10.239.0.2. 55175 > 10.225.2.8.67: BOOTP/DHCP, Request from c9:31:cf:d8:af:ec, length 308 17:42:23.932246 IP 10.225.2.8.67 > 10.239.0.2. 67 : BOOTP/DHCP, Reply, length 300 Someone can help me to solve this problem Thanks in advance Thomas
