Port Binding

12.1

Overview

This chapter describes how to configure the port binding settings.

Port binding allows you to aggregate port connections into logical groups. You may bind WAN PVCs

to Ethernet ports and WLANs to specify how traffic is forwarded. Different ATM QoS settings can be

specified for each WAN PVC to meet bandwidth requirements for the type of traffic to be

transferred.

For example, three port binding groups could be created on the device (R1) for three different WAN

PVC connections. The first PVC (PVC0) is for non time-sensitive data traffic. The second and third

PVCs (PVC1 and PVC2) are for time sensitive Media-On-Demand (MOD) video traffic and VoIP

traffic, respectively.

If a WAN PVC is bound to an ethernet port, traffic from the ethernet port will only be forwarded

through the specified WAN PVC and vice versa. If a port is not in a port binding group, traffic to and

from the port will be forwarded according to the routing table. See the tutorial section (

Section

on

page 37

) for more details on configuring port binding for multiple WAN connections.

Active

Activate or deactivate port binding for the port binding group.

Group Index

Select the index number for the port binding group.

When a port is assigned to a port binding group, traffic will be forwarded to the other

ports in the group, but not to ports in other groups. If a port is not included in any

groups, traffic will be forwarded according to the routing table.

ATM VCs

Select the ATM VC (PVC) to include in the port binding group. Each ATM VC can only

be bound to one group.

Ethernet

Select the Ethernet (Eth) ports to include in the port binding group. Each Ethernet

port can only be bound to one group.

Wireless LAN

Select the WLAN (AP) connection to include in the port binding group. Additional APs

can be enabled on the

More AP

Dynamic DNS Setup

13.1

Overview

Dynamic DNS allows you to update your current dynamic IP address with one or many dynamic

DNS services so that anyone can contact you (in NetMeeting, CU-SeeMe, etc.). You can also access

your FTP server or Web site on your own computer using a domain name (for instance

myhost.dhs.org, where myhost is a name of your choice) that will never change instead of using an

IP address that changes each time you reconnect. Your friends or relatives will always be able to

call you even if they don't know your IP address.

First of all, you need to have registered a dynamic DNS account with www.dyndns.org. This is for

people with a dynamic IP from their ISP or DHCP server that would still like to have a domain name.

The Dynamic DNS service provider will give you a password or key.

13.1.1

What You Can Do in the DDNS Screen

Use the

Dynamic DNS

screen (

Section 13.2 on page 165

) to enable DDNS and configure the DDNS

settings on the AMG1302/AMG1202-TSeries.

13.1.2

What You Need To Know About DDNS

DYNDNS Wildcard

Enabling the wildcard feature for your host causes *.yourhost.dyndns.org to be aliased to the same

IP address as yourhost.dyndns.org. This feature is useful if you want to be able to use, for example,

www.yourhost.dyndns.org and still reach your hostname.

If you have a private WAN IP address, then you cannot use Dynamic DNS.

13.2

The Dynamic DNS Screen

Use this screen to change your AMG1302/AMG1202-TSeries’s DDNS. Click
