Not really sure what you want, but if you try to write a rule for forwarding 
packets which destination Port 80 to your internal web server, try this 
one:

$IPT -t nat -A PREROUTING -p tcp --dport 80 -j DNAT --to-destination 
192.168.247.5:80

If you know your external fw-IP you can specify it in the rule:

$IPT -t nat -A PREROUTING -p tcp --dport 80 -d 202.138.128.xxx -j DNAT 
--to-destination 192.168.247.5:80
