NAME
tcpri - Shorewall file
SYNOPSIS
/etc/shorewall/tcpri
DESCRIPTION
This file is used to specify the priority of traffic for simple traffic
shaping (TC_ENABLED=Simple in shorewall.conf[1](5)). The priority band
of each packet is determined by the last entry that the packet matches.
If a packet doesn't match any entry in this file, then its priority
will be determined by its TOS field. The default mapping is as follows
but can be changed by setting the TC_PRIOMAP option in
shorewall.conf[1](5).
TOS Bits Means Linux Priority BAND
------------------------------------------------------------
0x0 0 Normal Service 0 Best Effort 2
0x2 1 Minimize Monetary Cost 1 Filler 3
0x4 2 Maximize Reliability 0 Best Effort 2
0x6 3 mmc+mr 0 Best Effort 2
0x8 4 Maximize Throughput 2 Bulk 3
0xa 5 mmc+mt 2 Bulk 3
0xc 6 mr+mt 2 Bulk 3

0x10 8 Minimize Delay 6 Interactive 1
0x12 9 mmc+md 6 Interactive 1
0x14 10 mr+md 6 Interactive 1
0x16 11 mmc+mr+md 6 Interactive 1
0x18 12 mt+md 4 Int. Bulk 2
0x1a 13 mmc+mt+md 4 Int. Bulk 2
0x1c 14 mr+mt+md 4 Int. Bulk 2
0x1e 15 mmc+mr+mt+md 4 Int. Bulk 2
The columns in the file are as follows.
BAND - {1|2|3}
Classifies matching traffic as High Priority (1), Medium Priority
(2) or Low Priority (3). For those interfaces listed in
shorewall-tcinterfaces[2](5), Priority 2 traffic will be deferred
so long and there is Priority 1 traffic queued and Priority 3
traffic will be deferred so long as there is Priority 1 or Priority
2 traffic to send.
PROTO - protocol
Optional. The name or number of an IPv4 protocol.
PORT(S) - port [,...]
Optional. May only be given if the the PROTO is TCP (6), UDP (17),
DCCP (33), SCTP (132) or UDPLITE (136). A list of one or more port
numbers or service names from /etc/services. Port ranges of the
form lowport:highport may also be included.
ADDRESS - [address]
Optional. The IP or MAC address that the traffic originated from.
MAC addresses must be given in Shorewall format. If this column
contains an address, then the PROTO, PORT(S) and INTERFACE column
must be empty ("-").
INTERFACE - [interface]
Optional. The logical name of an interface that traffic arrives
from. If given, the PROTO, PORT(S) and ADDRESS columns must be
empty ("-").
Note
INTERFACE classification of packets occurs before
classification by PROTO/PORT(S)/ADDRESS. So it is highly
recommended to place entries that specify INTERFACE at the top
of the file so that the rule about last entry matches is
preserved.
HELPER - [helper]
Optional. Names a Netfiler protocol helper module such as ftp, sip,
amanda, etc. A packet will match if it was accepted by the named
helper module. You can also append "-" and a port number to the
helper module name (e.g., ftp-21) to specify the port number that
the original connection was made on.
