Hello. Freeradius 2.1.6 Below of the message translated and not translated code of dhcp-packet from client soho-router TrendNet 631BRP. As i can see, the main problem is a wrong order (for freeradius rules) of dhcp options and that's why such packet did not recognized and did not accepted. When packet is arriving i see "Unknown, or badly formatted DHCP packet". How to fix this? P.S. sorry for my english. ====not translated============== 0000 00 04 23 cc 33 98 00 1b 11 97 74 7e 08 00 45 00 ..#.3... ..t~..E. 0010 01 48 09 78 00 00 40 11 72 5a 59 de a5 01 59 de .H.x..@. rZY...Y. 0020 a5 15 00 43 00 43 01 34 a8 46 01 01 06 01 7c 5e ...C.C.4 .F....|^ 0030 42 a1 00 00 80 00 00 00 00 00 00 00 00 00 00 00 B....... ........ 0040 00 00 59 de e9 01 00 15 17 3a 0c d1 00 00 00 00 ..Y..... .:...... 0050 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ........ ........ 0060 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ........ ........ 0070 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ........ ........ 0080 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ........ ........ 0090 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ........ ........ 00a0 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ........ ........ 00b0 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ........ ........ 00c0 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ........ ........ 00d0 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ........ ........ 00e0 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ........ ........ 00f0 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ........ ........ 0100 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ........ ........ 0110 00 00 00 00 00 00 63 82 53 63 0c 06 42 65 69 72 ......c.
