Hello,
Your first step would be
Google.com. There you can find a lot of answers. Don't expect LQ users to provide you with step by step guides. You'll not get a lot of responses if doing so. On the other hand, if you've found a howto and are having trouble understanding or applying it, that's when you'll find us at our best. You can have a look at
HowtoForge.com for some great step by step guides. In other words, put in some work and post what you've tried/configured/set up and where it's failing.
Kind regards,
Eric
