# shorewall6-tos(5)

Shorewall6 Type of Service rules file

## 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**\[1\] (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**

Designates a connection mark. If omitted, the packet mark's value is tested.
