9 /etc/shorewall[6]/tcpri

12 This file is used to specify the priority of traffic for simple traffic
13 shaping (TC_ENABLED=Simple in shorewall.conf[1](5)). Beginning with
14 Shorewall 5.2.7, the file allows ?FORMAT 2 which inserts a SPORT column
15 immediately to the right of the DPORT column.
16 The priority band of each packet is determined by the last entry that
18 the packet matches. If a packet doesn't match any entry in this file,
19 then its priority will be determined by its TOS field. The default
20 mapping is as follows but can be changed by setting the TC_PRIOMAP
21 option in shorewall.conf[1](5).

41 The columns in the file are as follows.
43 BAND - {1|2|3}
45 Classifies matching traffic as High Priority (1), Medium Priority
46 (2) or Low Priority (3). For those interfaces listed in
47 shorewall-tcinterfaces[2](5), Priority 2 traffic will be deferred
48 so long and there is Priority 1 traffic queued and Priority 3
49 traffic will be deferred so long as there is Priority 1 or Priority
50 2 traffic to send.
51 PROTO - protocol[,...]
53 Optional. The name or number of an IPv4 protocol.
54 Beginning with Shorewall 4.5.12, this column can accept a
56 comma-separated list of protocols.
57 DPORT - port [,...]
59 This column was named PORT prior to Shorewall 5.2.7. Both 'port'
60 and 'dport' may be used in the alternate input format[3].
61 Optional. May only be given if the the PROTO is TCP (6), UDP (17),
63 DCCP (33), SCTP (132) or UDPLITE (136). A list of one or more port
64 numbers or service names from /etc/services. Port ranges of the
65 form lowport:highport may also be included. In format 1, packets
66 whose source or destination port matches the specified port(s) are
67 assigned to the band given in the BAND column.
68 SPORT - port [,...]
70 Only present in file format 2. Optional. May only be given if the
71 the PROTO is TCP (6), UDP (17), DCCP (33), SCTP (132) or UDPLITE
72 (136). A list of one or more port numbers or service names from
73 /etc/services. Port ranges of the form lowport:highport may also be
74 included.
75 ADDRESS - [address]
77 Optional. The IP or MAC address that the traffic originated from.
78 MAC addresses must be given in Shorewall format. If this column
79 contains an address, then the PROTO, PORT(S) and INTERFACE column
80 must be empty ("-").
81 INTERFACE - [interface]
83 Optional. The logical name of an interface that traffic arrives
84 from. If given, the PROTO, PORT(S) and ADDRESS columns must be
85 empty ("-").
86 Note
88 INTERFACE classification of packets occurs before
89 classification by PROTO/PORT(S)/ADDRESS. So it is highly
90 recommended to place entries that specify INTERFACE at the top
91 of the file so that the rule about last entry matches is
92 preserved.
93 HELPER - [helper]
95 Optional. Names a Netfilter protocol helper module such as ftp,
96 sip, amanda, etc. A packet will match if it was accepted by the
97 named helper module. You can also append "-" and a port number to
98 the helper module name (e.g., ftp-21) to specify the port number
99 that the original connection was made on.
