Let’s say I have a website ‘http://www.myoffice.com’ – this is my external website.

Secondly, I have an internal website ‘http://www.bostonoffice.com’ – this is my internal office website.

I want all my external users to use the website – ‘http://www.myoffice.com’

When they type this address  it should get routed to ‘http://www.bostonoffice.com.’ What is the procedure to do this? I worked with DNS, but i don’t know the actual steps. Can anyone help me out please ?
