Under Profile Selection , you can select commonly used upstream and downstream profiles. User-
defined allows you to manually specify the transfer rate at which data is downloaded from the In-
ternet ( Downstream ) and at which rate data is uploaded to the Internet ( Upstream ).

VLAN ID (only for VLAN connections)
In a virtual LAN (VLAN), the physical network (DSL) is divided into multiple logical networks. These
networks are on a single line, but they are logically separated and addressed via their VLAN IDs. This
is where you enter the
VLAN ID provided by your ISP.

Type of Internet connection
Specify whether and when an existing Internet connection should be disconnected. The option I use
a flat rate or traffic amount based tariff is intended for users with an Internet flat rate. When this
option is selected, the Gateway 400 is permanently connected to the Internet.
If you have a time-based tariff, select the option I use a time based tariff to avoid incurring high con-
nection costs. Select the option Disconnect connection automatically after [max. 10 minutes] idle
time to allow the Gateway 400 to automatically disconnect you from the Internet when no data is
being transmitted.

PPPoE Pass Through
PPPoE Pass Through allows the router to be operated in transparent mode; it also allows for an ad-
ditional Internet connection to be set up from the home network. You can also connect to the Inter-
net via any computer or router connected to the Gateway 400 even if that computer or router is
configured to use another ISP for Internet access.

Daily Auto-Disconnect
Daily Auto-Disconnect disconnects the Gateway 400 from the Internet daily at a specified time. This
setting preempts the forced disconnect initiated by the ISP after 24-hour Internet connections and
thus prevents unnecessary interruptions of ongoing calls. Forced disconnects are technically re-
quired in order to release IP addresses.

5.4.2 Dynamic DNS
This screen dialog lists the configured Dynamic DNS accounts. Dynamic DNS is an Internet service
which allows you to set up a fixed name as a pseudonym for a dynamically assigned IP address, as
is typically the case for Internet addresses. Using Dynamic DNS and so-called
port forwardings
( Chapter 5.7.2, page 36 ), you can make servers in your local network statically visible on the Inter-
net, or access the contents of USB mass storage devices from the Internet under a fixed name.
To use Dynamic DNS, you first need to set up an account with a Dynamic DNS provider (such as
dyndns.org). You can then use this account to set up a new Dynamic DNS account on the Gateway
400. To do this, click
New . Select the desired provider from the Provider drop-down menu. Enter the
data supplied by your provider in the following fields and click Save .
Attention
Please note that any server in your home network that is statically visible on the Internet
through Dynamic DNS is a potential target for malicious attacks by unauthorized third
parties!
Make sure you secure your Dynamic DNS account with a strong password. Always keep
your security software up to date, and investigate unusual events immediately. Stay in-
formed about the latest security issues.
