Your company policy might dictate how you deploy GroupWise Mobile Server within your network configuration. There are several configuration options available; however, Novell recommends the configuration described in this section using a demilitarized zone (DMZ) or screened subnet with the Secure Gateway. The DMZ is a computer or small subnetwork that sits between a trusted internal network, such as a corporate private LAN, and an untrusted external network, such as the public Internet. The Secure Gateway allows you to connect to a server in the DMZ then connect the computer in the DMZ to a computer behind the corporate private LAN.
The Secure Gateway is a communications infrastructure component of GroupWise Mobile Server. Secure Gateway offers secure and scalable communications between mobile devices and servers.The benefits of this configuration include simplicity, performance, and security.
The installation application allows you to quickly install and configure the Secure Gateway.
A single outbound-initiated TCP/IP port is open in the firewall and you can restrict it to a single IP address.
DNS routing makes the experience simple whether the client is internal or external.
The Secure Gateway does not significantly reduce performance.
The Secure Gateway handles load-balanced connections to multiple Mobile Gateway servers. You can assign the round-robin connections based on “next available” or server load.
The Secure Gateway is highly secure. This configuration securely controls communications between the DMZ and the enterprise.
This configuration routes traffic to a different protocol and port, thereby restricting any pass-through attempts to the firewall.
