NAME

       tcfilters - shorewall6 u32 classifier rules file

SYNOPSIS

       /etc/shorewall6/tcfilters

DESCRIPTION

       Entries in this file cause packets to be classified for traffic shaping.

       Beginning with Shorewall 4.4.15, the file may contain entries for both IPv4 and IPv6. By default, all rules apply to IPv6 but that can be
       changed by inserting a line as follows:

       IPV4
	   Following entries apply to IPv4.

       IPV6
	   Following entries apply to IPv6

       ALL
	   Following entries apply to both IPv4 and IPv6. Each entry is processed twice; once for IPv4 and once for IPv6.

       The columns in the file are as follows (where the column name is followed by a different name in parentheses, the different name is used in
       the alternate specification syntax).

       CLASS - interface:class
	   The name or number of an interface defined in shorewall6-tcdevices[1](5) followed by a class number defined for that interface in
	   shorewall6-tcclasses[2](5).

       SOURCE - {-|address}
	   Source of the packet. May be a host or network address. DNS names are not allowed.

       DEST - {-|address}}
	   Destination of the packet. May be a host or network address. DNS names are not allowed.

       PROTO - {-|protocol-number|protocol-name|all}
	   Protocol.

       DEST PORT (dport) - [-|port-name-or-number]
	   Optional destination Ports. A Port name (from services(5)) or a port number; if the protocol is icmp, this column is interpreted as the
	   destination icmp-type(s).

       SOURCE PORT (sport) - [-|port-name-or-number]
	   Optional source port.

       TOS - [-|tos]
	   Optional - specifies the value of the TOS field. The tos value can be any of the following:

	   o   tos-minimize-delay

	   o   tos-maximuze-throughput

	   o   tos-maximize-reliability

	   o   tos-minimize-cost

	   o   tos-normal-service

	   o   hex-number

	   o   hex-number/hex-number

	   The hex-numbers must be exactly two digits (e.g., 0x04)x.

       LENGTH - [-|number]
	   Optional. Must be a power of 2 between 32 and 8192 inclusive. Packets with a total length that is strictly less than the specified
	   number will match the rule.

EXAMPLE

       Example 1:
	   Place all 'ping' traffic on interface 1 in class 10. Note that ALL cannot be used because IPv4 ICMP and IPv6 ICMP are two different
	   protocols.

		       #CLASS	 SOURCE    DEST 	PROTO	DEST
		      # 				       PORT

		      IPV4

		      1:10	0.0.0.0/0 0.0.0.0/0    icmp    echo-request
		      1:10	0.0.0.0/0 0.0.0.0/0    icmp    echo-reply

		      IPV6

		      1:10	::/0	  ::/0	       icmp6   echo-request
		      1:10	::/0	  ::/0	       icmp6   echo-reply
