Overview

This step-by-step example will show how to set up a QMultiFlex-400™ point to multipoint
system as a whole. The QMultiFlex-400™ P2MP system comprises of a hub modem and
QFlex-400™ modems for the remotes.
The QMultiFlex-400™ supports up to 16 DVBS2X demodulators out of the box (depending
on software options). Further QMultiFlex-400™ units can be cascaded together to expand
this up to 128 demodulators. For the sake of simplicity in this example, only three remote
modems will be used. Once the configuration principles are grasped, more remotes can be
added.
The idea is to distribute the Internet connection at the hub to hosts at the remote sites.

The QMultiFlex-400™ is connected to the hub router with a VLAN trunk. The hub router
provides DHCP information to the remote PCs (IP, gateway and DNS addresses) and uses
PAT overload to connect them to the ISP office router.
