What You Need To Know
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.

Interface Group
13.1
Overview
By default, all LAN and WAN interfaces on the Device are in the same group and can communicate
with each other. Create interface groups to have the Device assign the IP addresses in different
domains to different groups. Each group acts as an independent network on the Device. This lets
devices connected to an interface group’s LAN interfaces communicate through the interface
group’s WAN or LAN interfaces but not other WAN or LAN interfaces.
13.1.1
What You Can Do in this Chapter
The
Interface Group
screens let you create multiple networks on the Device (
Section 13.2 on
page 199
).
13.2
The Interface Group Screen
You can manually add a LAN interface to a new group. Alternatively, you can have the Device
automatically add the incoming traffic and the LAN interface on which traffic is received to an
interface group when its DHCP Vendor ID option information matches one listed for the interface
group.
Use the
LAN
screen to configure the private IP addresses the DHCP server on the Device assigns to
the clients in the default and/or user-defined groups. If you set the Device to assign IP addresses
based on the client’s DHCP Vendor ID option information, you must enable DHCP server and
configure LAN TCP/IP settings for both the default and user-defined groups. See
Chapter 8 on page
133
for more information.

In the following example, the client that sends packets with the DHCP Vendor ID option set to MSFT
5.0 (meaning it is a Windows 2000 DHCP client) is assigned the IP address 192.168.2.2 and uses
the WAN VDSL_PoE/ppp0.1 interface.
