DESCRIPTION These options apply to match statements. at By default a match is attached to the parent of its parent class. For example, if its parent is a class directly under the interface, then the match is attached to the interface and is compared against all traffic of the interface. For nested classes, a match of a leaf, is attached to the parent class and is compared against all traffic of this parent class. With the at parameter, a match can be attached any class. The name parameter should be a class name. The name root attaches the match to the interface. class Defines the name of the class that will get the packets matched by this match. By default it is the name of the class the match statement appears under. Note There is also a class definition for traffic, see fireqos-class(5). syn, syns Match TCP SYN packets. Note that the tcp parameter must be specified. If the same match statement includes more protocols than TCP, then this match will work for the TCP packets (it will be silently ignored for all other protocols). For example, syn is ignored when generating the UDP filter in the below: match tcp syn match proto tcp,udp syn ack, acks Same as syn, but matching TCP ACK packets. proto, protocol, tcp, udp, icmp, gre, ipv6 Match the protocol in the IP header. tos, priority Match to TOS field of ipv4 or the priority field of ipv6. The tosid can be a value/mask in any format tc(8) accepts, or one of the following: · min-delay, minimize-delay, minimum-delay, low-delay, interactive · maximize-throughput, maximum-throughput, max-throughput, high-throughput, bulk · maximize-reliability, maximum-reliability, max-reliability, reliable · min-cost, minimize-cost, minimum-cost, low-cost, cheap, normal-service, normal Note There is also a class parameter called priority, see fireqos-params-class(5). mark (QOS) Match an iptables(8) MARK. Matching iptables(8) MARKs does not work on input interfaces. You can use them only on output. The IFB devices that are used for shaping inbound traffic do not have any iptables hooks to allow matching MARKs. If you try it, FireQOS will attempt to do it, but currently you will get an error from the tc(8) command executed. ports, sports, dports Match ports of the IP header. ports will create rules for matching source and destination ports (separate rules for each). dports matches destination ports, sports matches source ports. ip, net, host, src, dst Match IPs of the IP header. ip, net and host will create rules for matching source and destination IPs (separate rules for each). src matches source IPs and dst destination IPs. Note If the class these matches appear in are IPv4, then only IPv4 IPs can be used. To override use match6 ... src/dst *IPV6_IP* Similarly, if the class is IPv6, then only IPv6 IPs can be used. To override use match4 ... src/dst *IPV4_IP*. You can mix IPv4 and IPv6 in any way you like. FireQOS supports inheritance, to figure out for each statement which is the default. For example: interface46 eth0 lan output rate 1Gbit # ipv4 and ipv6 enabled class voip # ipv4 and ipv6 class, as interface is both match udp port 53 # ipv4 and ipv6 rule, as class is both match4 src # ipv4 only rule match6 src 2001:db8::1 # ipv6 only rule class4 realtime # ipv4 only class match src # ipv4 only rule, as class is ipv4-only class6 servers # ipv6 only class match src 2001:db8::2 # ipv6 only rule, as class is ipv6-only To convert an IPv4 interface to IPv6, just replace interface with interface6. All the rules in that interface, will automatically inherit the new protocol. Of course, if you use IP addresses for matching packets, make sure they are IPv6 IPs too. prio (match) Note There is also a class parameter called prio, see fireqos-params-class(5). All match statements are attached to the interface. They forward traffic to their class, but they are actually executed for all packets that are leaving the interface (note: input matches are actually output matches on an IFB device). By default, the priority they are executed, is the priority they appear in the configuration file, i.e. the first match of the first class is executed first, then the rest matches of the first class in the sequence they appear, then the matches of the second class, etc. It is sometimes necessary to control the order of matches. For example, when you want host to be assigned the first class, except port tcp/1234 which should be assigned the second class. The following will not work: interface eth0 lan output rate 1Gbit class high match host class low match host port 1234 # Will never match In this case, the first match is assigned priority 10 and the second priority 20. The second match will never match anything, since all traffic for the host is already matched by the first one. Setting an explicit priority allows you to change the order in which the matches are executed. FireQOS gives priority 10 to the first match of every interface, 20 to the second match, 30 to the third match, etc. So the default is 10 x the sequence number. You can set prio to overwrite this number. To force executing the second match before the first, just set a lower priority for it. For example, this will cause the desired behaviour: interface eth0 lan output rate 1Gbit class high match host class low match host port 1234 prio 1 # Matches before host-only
