Thanks and Regards Amit haoda <haoda@64translator.com> wrote: Hi Mr. Amit, I think the content of the Relay option is invalid. The length of it is only 38. It does not include the following options after SID option. And please also check the data from offset 0x007c.(from "ddba") it is a invalid option number. 0002 000e ................ 0x0070: 0001 0001 0004 93e0 0050 da91 ddba 0007 .........P...... 0x0080: 0001 0000 0300 0c00 018a 9200 0000 1000 ................ 0x0090: 0000 2e00 0b00 1c03 0100 0300 0000 0000 ................ 0x00a0: 0000 01c6 237b 3269 983c 6473 4833 6651 ....#{2i. 0x00b0: dcb0 74 Ethereal looks can't decode it properly.
