how to port forward - correctly


Hi everyone. I have a webserver behind a linux firewall. I can't get to it from the internet. When I enter my URL, say www.foo.com, it returns an error "The page cannot be displayed"

Following is a simple diagram(might not display correctly) of what I'm trying to do:
............
.Internet.
............
|
| 24.111.111.111
_____|__________
| firewall | 80 |
|-----------------------|
| HTTP | 8099 |
----------|-------------
| 192.168.1.1
|
--------|-------|-------
|
| 192.168.1.2
------|-----
| WWW |
------------

Following is my port forwarding rule:
Proto: TCP
Source Port: 80
Destination IP: 192.168.1.2
Destination Port: 80

If I run an ipchains -C (to test rules), with corresponding IP source/destination and port 80, it says "accepted". This means that my network is open for incoming(internet) request through port 80.

From my firewall, I'm able to ping say, yahoo.com, and to my 24.111.111.111 from the internet.

From my 192.168.1.1 network, I'm able to get to my webserver either through its IP address or FQDN. But when I'm in the internet, I can't get to my webserver.

What am I doing wrong? Please advise. I'm kinda new with linux and setting up webservers. One more thing,

Any suggestion or comments are welcome.

Thanks,
Angel
