Virtual IP Address

Hey guys, i have an issue that's probably really easy to fix. I"m trying to setup ssl on one of my sites. I am having a problem getting the virtual IP address to work. When I set the virtual host to the new ip address, I get a 403 error message. When I set the host back to the default shared IP address, it works fine.

Can someone tell me the correct way to add virtual IP address? I followed the steps in the webmin/virtual documentation and it's not working
