[CentOS] iptables question

I''ve added the following and it still isn''t working

iptables -t nat -I PREROUTING -p tcp -m tcp --dport 8443 -j DNAT
--to-destination 192.168.0.2:8443
iptables -A FORWARD -d 192.168.0.1 -p tcp -m tcp --dport 8443 -j ACCEPT

I''ve enabled forwarding - not sure if it''s needed but
it''s there just in
case.

Try this tutorial its long but thorough .
http://iptables-tutorial.frozentux.net/iptables-tutorial.html
There are several examples that you should be able to craft to fit your
needs.
First you make a forward chain and then prerouting chain with DNAT.
Be advised if you don''t have console access you can cut off your access
very easy with iptables.
