## Name

tos — Shorewall6 Type of Service rules file

## Synopsis

`/etc/shorewall6/tos`

## Description

This file defines rules for setting Type Of Service (TOS). Its use is deprecated, beginning in Shorewall 4.5.1, in favor of the TOS target in shorewall6-mangle (5).

The columns in the file are as follows.

SOURCE - {all|address]|all:address|$FW}

  If all, may optionally be followed by ":" and an IP address, a MAC address, a subnet specification or the name of an interface.

  Example: all:2002:ce7c::92b4:1::2

  MAC addresses must be prefixed with "~" and use "-" as a separator.

  Example: ~00-A0-C9-15-39-78

DEST - {all|address]|all:address}

  Example: 2002:ce7c::92b4:1::2

PROTOCOL - proto-name-or-number

  Protocol name or number.

SOURCE PORT(S) - {-|port|lowport:highport}

  Source port or port range. If all ports, use "-".

DEST PORT(S) - {-|port|lowport:highport}

  Destination port or port range. If all ports, use "-"

TOS - tos

  Must be one of the following;

              tos-minimize-delay (16)
              tos-maximize-throughput (8)
              tos-maximize-reliability (4)
              tos-minimize-cost (2)
              tos-normal-service (0)

  To specify more than one flag, add their values together and specify the numeric result.

MARK - [!]value[/mask][:C]

  If you don't want to define a test but need to specify anything in the following columns, place a "-" in this field.

  !

    Inverts the test (not equal)

  value

    Value of the packet or connection mark.

  mask

    A mask to be applied to the mark before testing.

  :C
