DMZ/LAN Configuration

Usingthis configuration, the Telecommuting Module is located on the DMZ of your firewall, and connected to it
withone of the interfaces. The other interface is connected to your internal network. The Telecommuting Module
canhandle several networks on the internal interface even if they are hidden behind routers. No networks on other
interfaceson the firewall can be handled.
Thisconfiguration is used to enhance the data throughput, since the traffic only needs to pass your firewall once.
Thisconfiguration can only support one local network.

outsideworld on the other.
