| This target is an extension of the QUEUE target. As opposed to QUEUE, it allows |
| you to put a packet into any specific queue, identified by its 16-bit queue |
| number. |
| It can only be used with Kernel versions 2.6.14 or later, since it requires |
| the |
| .B |
| nfnetlink_queue |
| kernel support. The \fBqueue-balance\fP option was added in Linux 2.6.31, |
| \fBqueue-bypass\fP in 2.6.39. |
| .TP |
| \fB\-\-queue\-num\fP \fIvalue\fP |
| This specifies the QUEUE number to use. Valid queue numbers are 0 to 65535. The default value is 0. |
| .PP |
| .TP |
| \fB\-\-queue\-balance\fP \fIvalue\fP\fB:\fP\fIvalue\fP |
| This specifies a range of queues to use. Packets are then balanced across the given queues. |
| This is useful for multicore systems: start multiple instances of the userspace program on |
| queues x, x+1, .. x+n and use "\-\-queue\-balance \fIx\fP\fB:\fP\fIx+n\fP". |
| Packets belonging to the same connection are put into the same nfqueue. |
| .PP |
| .TP |
| \fB\-\-queue\-bypass\fP |
| By default, if no userspace program is listening on an NFQUEUE, then all packets that are to be queued |
| are dropped. When this option is used, the NFQUEUE rule is silently bypassed instead. The packet |
| will move on to the next rule. |
