NAME
tcpri - Shorewall6 file
SYNOPSIS
/etc/shorewall6/tcpri
DESCRIPTION
This file is used to specify the priority band of traffic for simple traffic shaping (TC_ENABLED=Simple
in shorewall6.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
shorewall6.conf[1](5).
TOS Bits Means Linux Priority BAND

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 shorewall6-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.
Beginning with Shorewall 4.5.12, this column can accept a comma-separated list of protocols.
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 Netfilter 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.
