Note my patch has nothing to do with the man page, its already up2date.
I usually dont read the Fine manuals, do you ?
Try :
iptables -t nat -A PREROUTING -p tcp --dport 1234 -j REDIRECT --help
REDIRECT target options:
--to-ports <port>[-<port>]
Port (range) to map to.
You see [--random] is missing.
