Architecture: use a DMZ
This example shows you how to create a remote RoundCube for Internet remote users access service using 2 artica servers.
The deal is to play with DNS servers as the internal DNS server (that should be an Artica DNS server) is able to resolve the RoundCube WebMail service to the internal address and the Public DNS server will resolve the web site name as the DMZ server.
In this case mobile users will type the same Web site address in order to access to the WebMail.
The first service is the mail server and provide WebMail directly on the mail server for internal users.
The second service is stored on a DMZ and is designed to provide WebMail access for external users.
