A quick way to enable http access to vm

Run the following commands:

iptables -I INPUT -i eth1 -p tcp -m tcp --dport 80 -j ACCEPT

To make the changes persist, go to /etc/sysconfig/ and add to the following line to iptables:

-A INPUT -i eth1 -p tcp -m tcp --dport 80 -j ACCEPT

Then, restart the webserver:

service httpd restart

And now you can access out of VirtualBox.
