How to open port 80

Hello,
I recently setup an Apache webserver on my Red Hat Linux 7.3 Box. I can serve webpages across my LAN (192.168.0.X) but when I type in my IP address, it doesn't display the page. I tried to change my firewall configuration but it always goes back to HIGH instead of MEDIUM or NO FIREWALL. I tried a port scan and can only find one port open: 21. It seems that my DSL modem has a built-in FTP server. How can I open port 80? Thanks for any help.

it sounds like your webserver isn't binding to your external ip address. Your best bet would be to check out your httpd.conf file. This file should be in /etc/httpd/conf/. You can configure apache to listen on a specified ip address by using the format:
listen x.x.x.x:80 or just: listen 80
Hope that helps

Maybe some bad news. Some DSL providers in some areas block port 80. Check the fine print in your terms of service (TOS). Many residential service contracts do not allow Server activities.
Summary: Your firewall is still the problem. To verify this, you can disable the firewall for a short time and you will see, port 80 will be OK. Go to "START" -> System Settings -> Server settings -> Services....
