       tcpri - Shorewall6 file




       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

           TOS     Bits  Means                    Linux Priority    BAND

       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.

       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 ("-").

               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

       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.
