DESCRIPTION <\/a> <\/h2>\n

This file is used to specify the priority of traffic for simple traffic shaping (TC_ENABLED=Simple in shorewall.conf<\/font><\/b> [1]<\/font><\/small> (5)). Beginning with Shorewall 5.2.7, the file allows ?FORMAT 2 which inserts a SPORT column immediately to the right of the DPORT column.<\/font><\/p>\n

The priority band of each packet is determined by the last<\/b> 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<\/font> shorewall.conf<\/font><\/b> [1]<\/font><\/small> (5).<\/font><\/p>\n

The columns in the file are as follows.<\/font><\/p>\n

BAND<\/b> \u2212 {1<\/b>|2<\/b>|3<\/b>}<\/font><\/p>\n

Classifies matching traffic as High Priority (1), Medium Priority (2) or Low Priority (3). For those interfaces listed in<\/font> shorewall\u2212tcinterfaces<\/font><\/b> [2]<\/font><\/small> (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.<\/font><\/p>\n

PROTO<\/b> \u2212 protocol<\/i>[,…]<\/font><\/p>\n

Optional. The name or number of an IPv4 protocol<\/i>.<\/font><\/p>\n

Beginning with Shorewall 4.5.12, this column can accept a comma\u2212separated list of protocols.<\/font><\/p>\n

DPORT \u2212 port<\/i> [,…]<\/font><\/p>\n

This column was named PORT prior to Shorewall 5.2.7. Both ‘port’ and ‘dport’ may be used in the<\/font> alternate input format<\/font><\/b> [3]<\/font><\/small> .<\/font><\/p>\n

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<\/i>:highport<\/i> may also be included. In format 1, packets whose source or destination port matches the specified port<\/i>(s) are assigned to the band given in the BAND column.<\/font><\/p>\n

SPORT \u2212 port<\/i> [,…]<\/font><\/p>\n

Only present in file format 2. 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<\/i>:highport<\/i> may also be included.<\/font><\/p>\n

ADDRESS \u2212 [address<\/i>]<\/font><\/p>\n

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 (“\u2212”).<\/font><\/p>\n

INTERFACE \u2212 [interface<\/i>]<\/font><\/p>\n

Optional. The logical name of an interface<\/i> that traffic arrives from. If given, the PROTO, PORT(S) and ADDRESS columns must be empty (“\u2212”).<\/font><\/p>\n

Note<\/big><\/b>
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<\/i> is preserved.<\/font><\/p>\n

HELPER<\/big><\/b> \u2212 [helper<\/i>]<\/big><\/font><\/p>\n

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 “\u2212” and a port number to the helper module name (e.g., ftp\u221221) to specify the port number that the original connection was made on.<\/big><\/font><\/p>\n
