magento redirecting to internal ip from public ip

[icon_boy]

Hi all,

i was hoping someone can help me, I can access magento from the internal ip, but as soon as I try to access it via a public ip, I get a redirect to the internal ip.

I know part forwarding is setup correctly, as I can reach phpmyadmin via the external ip address, 

apache virtualhost is set up as follows:

<VirtualHost *:80>
    DocumentRoot /var/www/magento2
    <Directory /var/www/magento2/>
       Options Indexes FollowSymLinks MultiViews
       AllowOverride All
    </Directory>
</VirtualHost>

an help most appreciated

thanks

Ok I got it working as I am using Ubuntu 14.04 - the root to the website should have been within /html
