The firewall port and the port that apache binds to is two completely different things.
You can explain it like this…
You have a number of doors in a hallway,
Your firewall controls what doors are locked, and what doors are open.
The configuration file for your application (in this case apache) tells the application what door it should stand behind to greet the visitors.
So changing the port from 80 to 8080 in the firewall, will only cause the firewall to lock the door with the number ‘80’ sign on and unlock ‘8080’… It won’t tell apache to move to door ‘8080’.
For that you need to change the configuration in apache. To do that, you can either change it in the web server configuration in Interworx web GUI. Or go to /etc/httpd/conf/httpd.conf and change ‘Listen 80’ to ‘Listen 8080’ and restart the service with ‘service httpd restart’. If you’re not experienced with changing in config files, I highly recommend using the InterWorx Web GUI, and navigate to ‘https://your.serveradress.com:2443/nodeworx/http’ and change ‘HTTP port’ from ‘80’ to ‘8080’, and restart the service with the restart button.
