Owncloud using fedora repository on centos

OK I have been trying to get my server centos to be seen on the outside of my home. I have centos 6 64 bit minimal install. This is how I get owncloud installed on centos:

Fisrt I went here:

http://www.howtoforge.com/installing...entos-6.2-lamp

Then this:

cd /etc/yum.repos.d/
wget http://download.opensuse.org/reposit...community.repo
yum install owncloud

## RHEL/CentOS 6 32-Bit ##
# wget http://download.fedoraproject.org/pu...6-8.noarch.rpm
# rpm -ivh epel-release-6-8.noarch.rpm

## RHEL/CentOS 6 64-Bit ##
# wget http://download.fedoraproject.org/pu...6-8.noarch.rpm
# rpm -ivh epel-release-6-8.noarch.rpm

So I install owncloud with no errors now. But I was wondering if it has anything to do with
fedora? Debian I can get it up and running. But my freind needs centos for the drivers.

Like I said I can get all installed but when I put:

https://192.168.0.2.owncloud.com/

When I put it in my browser it will not load. I tried /etc/sysconfig/network-scripts/ifcfg-eth0

But have no idea how to set it up.
