PPP Interfaces
Use PPPoE/PPTP interfaces to connect to your ISP. This way, you do not have to
install or manage PPPoE/PPTP software on each computer in the network.
Figure 156
Example: PPPoE/PPTP Interfaces
PPPoE/PPTP interfaces are similar to other interfaces in some ways. They have an
IP address, subnet mask, and gateway used to make routing decisions; they
restrict bandwidth and packet size; and they can verify the gateway is available.
There are two main differences between PPPoE/PPTP interfaces and other
interfaces.
•
You must also configure an ISP account object for the PPPoE/PPTP interface to
use.
Each ISP account specifies the protocol (PPPoE or PPTP), as well as your ISP
account information. If you change ISPs later, you only have to create a new ISP
account, not a new PPPoE/PPTP interface. You should not have to change any
network policies.
•
You do not set up the subnet mask or gateway.
PPPoE/PPTP interfaces are interfaces between the ZyWALL and only one
computer. Therefore, the subnet mask is always 255.255.255.255. In addition,
the ZyWALL always treats the ISP as a gateway.
At the time of writing, it is possible to set up the IP address of the gateway (ISP)
using CLI commands but not in the Web Configurator.
Service
This is the type of setting that references the selected object. Click a
service’s name to display the service’s configuration screen in the main
window.
Priority
If it is applicable, this field lists the referencing configuration item’s
position in its list, otherwise
N/A
displays.
Name
This field identifies the configuration item that references the object.
Description
If the referencing configuration item has a description configured, it
displays here.

Interface
Properties
Interface
Name
Specify a name for the interface. It can use alphanumeric characters,
hyphens, and underscores, and it can be up to 11 characters long.
Base Interface
Select the interface upon which this PPP interface is built.
Note: Multiple PPP interfaces can use the same base interface.
Description
Enter a description of this interface. It is not used elsewhere. You can
use alphanumeric and
()+/:=?!*#@$_%-
characters, and it can be
up to 60 characters long.
Connectivity
Nailed-Up
Select this if the PPPoE/PPTP connection should always be up. Clear
this to have the ZyWALL establish the PPPoE/PPTP connection only
when there is traffic. You might use this option if a lot of traffic needs
to go through the interface or it does not cost extra to keep the
connection up all the time.
Dial-on-
Demand
Select this to have the ZyWALL establish the PPPoE/PPTP connection
only when there is traffic. You might use this option if there is little
traffic through the interface or if it costs money to keep the
connection available.
ISP Setting
Account Profile
Select the ISP account that this PPPoE/PPTP interface uses. The drop-
down box lists ISP accounts by name. Use
Create new Object
if you
need to configure a new ISP account (see
Chapter 42 on page 655
for
details).
Protocol
This field is read-only. It displays the protocol specified in the ISP
account.
User Name
This field is read-only. It displays the user name for the ISP account.
Service Name
This field is read-only. It displays the PPPoE service name specified in
the ISP account. This field is blank if the ISP account uses PPTP.
IP Address
Assignment
Click
Advanced

Get
Automatically
Select this if this interface is a DHCP client. In this case, the DHCP
server configures the IP address automatically. The subnet mask and
gateway are always defined automatically in PPPoE/PPTP interfaces.
Use Fixed IP
Address
Select this if you want to specify the IP address manually.
IP Address
This field is enabled if you select
Use Fixed IP Address
.
Enter the IP address for this interface.
Metric
Enter the priority of the gateway (the ISP) on this interface. The
ZyWALL decides which gateway to use based on this priority. The
lower the number, the higher the priority. If two or more gateways
have the same priority, the ZyWALL uses the one that was configured
first.
