SharePoint Extranet Implementation in DMZ

Hello All,

I need to implement Extranet for our partners to access our documents. I have SP 2013 with SQL in another server inside my LAN. Now i want to add another SP server which is in DMZ (Extarnet). This new server will be an extended one from the LAN SP server. What are the best practices to do this?

Thanks,

Sai Siva Kumar
