NAME

       sanewall-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 shapping tricks[1].

       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.
