Should have read my reply closer before sending. Someone else had it.
You need to specify the protocol before the --dport command. Try
iptables -t nat -D PREROUTING -i eth0 -p tcp --dport 23 -j REDIRECT
--to-port 80
Don't know if it does what you want, but iptables has no problem with
it.
Hope this helps.
