NAME

       firehol-tosfix - apply suggested TOS values to packets

SYNOPSIS

       tosfix

DESCRIPTION

       The  tosfix helper command sets the Type of Service (TOS) field in packet headers based on
       the  suggestions  given  by   Erik   Hensema   in   iptables   and   tc   shaping   tricks
       (http://www.docum.org/docum.org/faq/cache/49.html).

       The following TOS values are set:

       • All  TCP  ACK packets with length less than 128 bytes are assigned Minimize-Delay, while
         bigger ones are assigned Maximize-Throughput

       • All packets with TOS Minimize-Delay, that are bigger than 512 bytes are set to Maximize-
         Throughput, except for short bursts of 2 packets per second

       The tosfix command must be used before the first router or interface.
