Configuring Gateway

Rainmail Server, when implemented as a Firewall, can control all network traffic from LAN to Internet and vice-versa. For this, the clients need to be told to direct all traffic to Internet through Rainmail Server. This can be done by setting Rainmail Server as Gateway in the client machine. 

In this section, we will see how DNS can be set as Rainmail Server for Windows 7. For other OS, a similar set of steps will be required.
