As I said in my previous message, NAT in the PREROUTING chain works only 
for connections from another host, not from the same host.

BTW, REDIRECT may change the destination address too. "DNAT --to :port" 
just changes the destination port.

"iptables -F" flushes only the default table, which is 'filter'. Your 
rule is in the 'nat' table. To flush it, run "iptables -t nat -F".
