> Please elaborate as what is wrong here in listing 3. Within the second line of the rule (@ih,80,16 set @ih,80,16 & 0x3f0 \) The mask 0x3f0 equates to 1,008 in decimal. (3 * 16**2) + (15 * 16**1) + (0 * 16^0) = 1,008 Here '**' indicates exponent. 1,008 is far larger than the 34 bit range that I covered. I understand that within NetFilter, there may be safeguards that which prevent writing beyond array bounds; but, that section of the rule still covers the bits that I did not wish to zero. Apologies, but I have not checked the code as of yet. sunny
