Ok here is what i did.
I added Listen 8080 to httpd.conf in /root/ispconfig/httpd/conf/ directory.
Then i restarted ispconfig.
but when i type http://mwavestruecombat.homelinux.com:8080/
i am still taken to the web servers root directory. Yes i do have the dns pointing to my internet ip (18.104.22.168). The dns is being hosted at dynDNS. What should i do?
