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.

Port Binding
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
screen (
Section 7.3 on page 98
).

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
Network Setting >
Dynamic DNS
. The screen appears as shown.
