Introduction

1.1 Overview

The GPT-2541GNAC GPON ONT combines high-speed Fiber Internet access with a built-in switch, a firewall and high-speed wireless networking capability. It has a phone port for making calls over the Internet (Voice over IP or VoIP). It also supports IPTV service when available from your service provider.

The following figure shows an application example of the Router. The Router is connected to a p

rovides IPTV, VoIP services as well as wired and wireless Internet access to home devices on the

Type the name of your PPPoE service here.

This field is not available for a PPPoA connection.

The Router supports PAP (Password Authentication Protocol) and CHAP (Challenge Handshake Authentication Protocol). CHAP is more secure than PAP; however, PAP is readily available on more platforms.

Use the drop-down list box to select an authentication protocol for outgoing calls. Options are:

AUTO - Your Router accepts either CHAP or PAP when requested by this remote node.

PAP - Your Router accepts PAP only.

CHAP - Your Router accepts CHAP only.

MSCHAP - Your Router accepts MSCHAP only. MS-CHAP is the Microsoft version of

the CHAP.

Enable NAT Select this check box to activate NAT on this connection.

Enable Fullcone NAT

This field is available only when you select Enable NAT. Select this check box to activate full cone NAT on this connection.

PPP IP extension Select this only if your service provider requires it. PPP IP extension extends the

service provider’s IP subnet to a single LAN computer.

• It lets only one computer on the LAN connect to the WAN.

• The public IP address from the ISP is forwarded through DHCP to the LAN computer instead of being used on the WAN PPP interface.

• It disables NAT and the firewall.

• DHCP tells the LAN computer to use the gateway as the default gateway and DNS server.

• The Router bridges IP packets between the WAN and LAN ports except packets destined for the Router’s LAN IP address.

In addition to the Router's built-in PPPoE client, you can select this to allow up to ten hosts on the LAN to use PPPoE client software on their computers to connect to the ISP via the Router. Each host can have a separate account and a public WAN IP address.

This is an alternative to NAT for application where NAT is not appropriate.

Universal Plug and Play (UPnP) is a distributed, open networking standard that uses TCP/IP for simple peer-to-peer network connectivity between devices. A UPnP device can dynamically join a network, obtain an IP address, convey its capabilities and learn about other devices on the network. In turn, a device can leave a network smoothly and automatically when it is no longer in use.

These are the rules the Router has created using UPnP.

Internal This is the internal port number that identifies a service.

You may enter a single port number or a range of port numbers to address of the desired server. The port number identifies a service; for example, web service is on port 80 and FTP on port 21. In some cases, such as for unknown services or where one server can support more than one service (for example both FTP and web service), it might be better to specify a range of port numbers. You can allocate a server IP address that corresponds to a port or a range of ports.

6.2 Port Triggering

Some services use a dedicated range of ports on the client side and a dedicated range of ports on the server side. With regular port forwarding you set a forwarding port in NAT to forward a service (coming in from the server on the WAN) to the IP address of a computer on the client side (LAN). The problem is that port forwarding only forwards a service to a single LAN IP address. In order to use the same service on a different LAN computer, you have to manually replace the LAN computer's IP address in the forwarding port with another LAN computer's IP address.

Chapter 6 Network Address Translation (NAT) 65

Trigger port forwarding solves this problem by allowing computers on the LAN to dynamically take

using the service. The Router records the IP address of a LAN computer that sends traffic to

turns the WAN to request a service with a specific port number and protocol (a "trigger" port). When the Router's WAN port receives a response with a specific port number and protocol ("open" port), the Router forwards the traffic to the LAN IP address of the computer that sent the request. After that computer’s connection for that service closes, another computer on the LAN can use the service in the same manner. This way you do not need to configure a new IP address each time you want a different LAN computer to use the application.

For example:

Figure 36 T

1 Jane requests a file from the Real Audio server (port 7070).

ort 7070 is a “trigger” port and causes the Router to record Jane’s computer IP address. The Router

2 P

associates Jane's computer IP address with the "open" port range of 6970-7170.

he Real Audio server responds using a port number ranging between 6970-7170.

3 T

4 The

5 On

Router forwards the traffic to Jane’s computer IP address.

ly Jane can connect to the Real Audio server until the connection is closed or times out. The Router times out in three minutes with UDP (User Datagram Protocol) or two hours with TCP/IP (Transfer Control Protocol/Internet Protocol).

10.3 Policy Routing

Traditionally, routing is based on the destination address only and the Router takes the shortest path to forward a packet. Policy routing allows the Router to override the default routing behavior and alter the packet routing based on the policy defined by the network administrator. Policy-based routing is applied to outgoing packets, prior to the normal routing.

You can use source-based policy routing to direct connections or distribute traffic among multiple paths for load sharing.
