Step 1: Installing the Quadro
Networking Overview
To establish a connection between the Internet and your local area network (LAN), an access router is needed. The Quadro IP PBX serves, among other functions, as an access
router, and will perform the task of connecting your LAN, or a group of one or more PCs, to
the wide area network (WAN) or the Internet. The Quadro will process and regulate the
data traffic between these two networks. All Quadro IP PBXs have one LAN port that can
connect to Ethernet hubs and switches on the LAN, allowing additional devices to be connected to the network.
The Quadro is a device with two sides: one side connects to your LAN, and the other side
connects to the Internet, or the WAN. Quadro’s firewall and Network Address Translation
(NAT) functionality protects your LAN from being seen from the Internet side making the
LAN private and secure.
The Ethernet WAN port transmits up to 10 Mbps, and the LAN port transmits at 10 Mbps or
100 Mbps. The ADSL and G.SHDSL WAN port will adjust to the transmission rates that are
available.
Every device within an IP network requires a unique IP address to identify itself. Since the
Quadro connects to both the LAN and the WAN, it has to be part of both networks, and
must have two IP addresses: one for the WAN side and one for the LAN side. The
Quadro’s integrated firewall/NAT functionality will hide the LAN IP address from the WAN
(Internet) side.
There are two ways of assigning an IP address: statically or dynamically.
A Static IP address is a fixed, manually assigned IP address that remains valid until
changed. If you plan to use the Quadro as your Internet access router, contact your Internet
Service Provider (ISP) to find out if a static IP address is assigned to your account. If so,
you will need this static IP address when configuring the Quadro device.
A dynamic IP address is a temporary address that is automatically assigned by your ISP
and will change periodically. If your ISP offers a dynamic IP address, the Quadro will act as
a DHCP client and will receive a new IP address from the ISP’s DHCP server or PPPoE
feature.
Please Note: A DHCP client is a piece of software that requests an IP address from a
DHCP server. A DHCP server assigns on request a unique IP address to a device. The
Quadro, like many routers, acts as a DHCP client on its WAN interface and as a DHCP
server on its LAN interface.
The Quadro must be visible to the Internet to be able to receive and send VoIP calls. When
the Quadro is placed in a private network, typically behind existing routers, it will by default
attempt to pass through the NAT of this router with its STUN (Simple Traversal of UDP over
NAT) feature. STUN will work without user configuration with the majority of basic routers.
In some scenarios, port forwarding on the router is required to make the Quadro accessible
to other Quadro devices and the Epygi SIP Server on the Internet. Another configuration
option is to use the Quadro as the Internet access router, connected directly to the WAN,
eliminating the traverse to the local NAT firewall.

LAN/WAN Connection Options
•
A Quadro IP PBX with an Ethernet WAN port behind a router, which is connected
to a cable or xDSL modem.
Fig. I-7: Configuration: Quadro behind a router
In this configuration (Fig.I-7), the IP router typically acts as a DHCP server for the LAN and
assigns the IP addresses to the PCs and other devices. The Quadro can be connected
through its WAN port directly to one of the router's LAN ports and will get an IP address
from the router. By default, the Quadro acts as a DHCP client on the WAN port.
Please Note: Since Quadro uses STUN by default, it will work with most basic
routers without any further configuration.
Please Note: Initially, the Admin PC must be connected to the Quadro LAN port to access
Web Management of the Quadro. Later, this PC can be moved to the router’s LAN. The
Quadro Web Management can be accessed from any PC in the router’s LAN as soon as
the firewall is disabled on the Quadro.

Please Note: The Admin PC is connected to the Quadro LAN port to access the Web
Management of the Quadro. After the initial configuration has been completed, this PC can
then be moved to the LAN and connect to the Quadro over a switch (see Fig.I-7). You also
may reach the Quadro for its first configuration from an Admin PC within the LAN, but this
may cause collisions in case of non-fitting IP addresses and competing DHCP servers.
Fig. I-9: Configuration: Quadro used as Internet Access Router with a switch connected to the LAN port
If the user already operates a router connected to the cable or DSL modem and has devices behind the router, the router is disconnected from the modem and the Quadro is inserted between the modem and the router (see Fig.I-9). The Quadro serves as an Internet
access router and DHCP server. The Quadro will be configured to connect directly to the
Internet through a cable or DSL modem. The router then is connected to the Quadro LAN
port.
