NAME

       sanewall-tos - set the Type of Service (TOS) of packets

SYNOPSIS

       tos value chain [rule-params]

DESCRIPTION

       The tos helper command sets the Type of Service (TOS) field in packet headers.

           Note
           There is also a tos parameter which allows matching TOS values within individual rules
           (see optional rule parameters: sanewall-rule-params(5)).

       The value can be an integer number (decimal or hexadecimal) or one of the descriptive
       values accepted by iptables (run iptables -j TOS --help for a list).

       The chain will be used to find traffic to mark. It can be any of the iptables built in
       chains belonging to the mangle table. The chain names are: INPUT, FORWARD, OUTPUT,
       PREROUTING and POSTROUTING. The names are case-sensitive.

       The rule-params define a set of rule parameters to match the traffic that is to be marked
       within the chosen chain. See optional rule parameters: sanewall-rule-params(5) for more
       details.

       Any tos commands will affect all traffic matched. They must be declared before the first
       router or interface.

EXAMPLES

           # set TOS to 16, packets sent by the local machine
           tos 16 OUTPUT

           # set TOS to 0x10 (16), packets routed by the local machine
           tos 0x10 FORWARD

           # set TOS to Maximize-Throughput (8), packets routed by the local
           #              machine, destined for port TCP/25 of 198.51.100.1
           tos Maximize-Throughput FORWARD proto tcp dport 25 dst 198.51.100.1
