+This target provides userspace logging of matching packets. When this
+target is set for a rule, the Linux kernel will multicast this packet
+through a
+.IR netlink
+socket. One or more userspace processes may then subscribe to various
+multicast groups and receive the packets.
+Like LOG, this is a "non-terminating target", i.e. rule traversal
+continues at the next rule.
+.TP
+\fB\-\-ulog\-nlgroup\fP \fInlgroup\fP
+This specifies the netlink group (1-32) to which the packet is sent.
+Default value is 1.
+.TP
+\fB\-\-ulog\-prefix\fP \fIprefix\fP
+Prefix log messages with the specified prefix; up to 32 characters
+long, and useful for distinguishing messages in the logs.
+.TP
+\fB\-\-ulog\-cprange\fP \fIsize\fP
+Number of bytes to be copied to userspace. A value of 0 always copies
+the entire packet, regardless of its size. Default is 0.
+.TP
+\fB\-\-ulog\-qthreshold\fP \fIsize\fP
+Number of packet to queue inside kernel. Setting this value to, e.g. 10
+accumulates ten packets inside the kernel and transmits them as one
+netlink multipart message to userspace. Default is 1 (for backwards
+compatibility).
