[ubuntu] Access to Webmin after IP change

view story

http://ubuntuforums.org – Sorry for the idiot question but just started with Linux (ubuntu server 12.04). I have vSphere 5 host running a couple Windows 08 servers and now ubuntu server. Plan is to use ubuntu for a simple web webserver (save $$$) I just finished a ubuntu LAMP server install and followed with a Webmin install. All went as expected and I was able to connect to Webmin. I then changed to a static IP using Wedmin but now cannot connect to the Webmin website using the new IP. I did restart the server and checked the IP - was changed to my static. Any ideas, what am I missing? (Hardware)
