NAME

SYNOPSIS

9       /etc/shorewall[6]/tcpri
10

DESCRIPTION

12       This file is used to specify the priority of traffic for simple traffic
13       shaping (TC_ENABLED=Simple in shorewall.conf[1](5)). The priority band
14       of each packet is determined by the last entry that the packet matches.
15       If a packet doesn't match any entry in this file, then its priority
16       will be determined by its TOS field. The default mapping is as follows
17       but can be changed by setting the TC_PRIOMAP option in
18       shorewall.conf[1](5).

39       The columns in the file are as follows.
40
41       BAND - {1|2|3}
42           Classifies matching traffic as High Priority (1), Medium Priority
43           (2) or Low Priority (3). For those interfaces listed in
44           shorewall-tcinterfaces[2](5), Priority 2 traffic will be deferred
45           so long and there is Priority 1 traffic queued and Priority 3
46           traffic will be deferred so long as there is Priority 1 or Priority
47           2 traffic to send.
48
49       PROTO - protocol[,...]
50           Optional. The name or number of an IPv4 protocol.
51
52           Beginning with Shorewall 4.5.12, this column can accept a
53           comma-separated list of protocols.
54
55       PORT(S) - port [,...]
56           Optional. May only be given if the the PROTO is TCP (6), UDP (17),
57           DCCP (33), SCTP (132) or UDPLITE (136). A list of one or more port
58           numbers or service names from /etc/services. Port ranges of the
59           form lowport:highport may also be included.
60
61       ADDRESS - [address]
62           Optional. The IP or MAC address that the traffic originated from.
63           MAC addresses must be given in Shorewall format. If this column
64           contains an address, then the PROTO, PORT(S) and INTERFACE column
65           must be empty ("-").
66
67       INTERFACE - [interface]
68           Optional. The logical name of an interface that traffic arrives
69           from. If given, the PROTO, PORT(S) and ADDRESS columns must be
70           empty ("-").
71
72               Note
73               INTERFACE classification of packets occurs before
74               classification by PROTO/PORT(S)/ADDRESS. So it is highly
75               recommended to place entries that specify INTERFACE at the top
76               of the file so that the rule about last entry matches is
77               preserved.
78
79       HELPER - [helper]
80           Optional. Names a Netfilter protocol helper module such as ftp,
81           sip, amanda, etc. A packet will match if it was accepted by the
82           named helper module. You can also append "-" and a port number to
83           the helper module name (e.g., ftp-21) to specify the port number
84           that the original connection was made on.
