Using PPTP encapsulation on Prestige
What is PPTP Client? 0
Microsoft's Point-to-Point Tunneling Protocol (PPTP) is a network protocol that enables the secure transfer of
data from a remote client to a private enterprise server by creating a VPN across TCP/IP network. PPTP
supports on-demand, multi-protocol, virtual private networking over public networks, such as the Internet.
This implementation of PPTP client is specifically for the French market where Alcatel's ANT (ADSL Network
Termination) is deployed. Most, if not all, broadband modems (ADSL and cable modem) are equipped with
Ethernet instead of RS-232 because RS-232 is too slow. It is therefore impossible to use them in the same way
as the traditional analog modem and ISDN TA. A mechanism is needed to transport the PPP frames from a PC
to the broadband modem over Ethernet. Before PPPoE was formalized, Alcatel came up with the idea of
building PPTP into their ANT for this purpose.
Instead of using the Internet to transport PPP frames anywhere in the world as originally envisioned, Alcatel's
solution uses PPTP only over the short haul between the PC and the modem over Ethernet. For the rest of the
connection, the PPP frames are transported with PPP over AAL5 (RFC 2364). The PPP connection, however, is
still between the PC and the ISP.
The various connections in this setup are depicted in the following diagram.

The PPTP client feature means the PPTP connection is initialized by the Prestige, so this connection is
transparent to the PPTP clients on the network. This eliminates the settings of every clients and does not matter
whether the computers on the network are Windows, Macintosh or even UNIX, all that is required is a standard
TCP/IP protocol stack. In fact, users are unaware that they are on a VPN, since the Prestige does all the VPN
work.
Setup the Prestige as a DHCP Relay
What is DHCP Relay?

Prestige 2302RL Support Notes
All contents copyright (c) 2007 ZyXEL Communications Corporation.
13
DHCP (Dynamic Host Configuration Protocol) allows a network device to obtain IP settings from a server. You
can configure the P-2602 as a DHCP server or DHCP relay.
When the P-2602 is configured as a DHCP server, it assigns IP address to clients on the LAN. When the P-2602
acts as a DHCP relay, it forwards client DHCP requests to the DHCP server and forwards the responds from the
DHCP server to the DHCP clients. The following figure shows an example.
Setup the Prestige as a DHCP Client
1. In SMT menu 3.2, select Relay in the DHCP field and enter the IP address of the DHCP server in the DHCP
Server Address field.

Configure an Internal Server Behind the Prestige
Introduction
SUA makes your LAN appear as a single machine to the outside world. However, you can make a server (such
as a web server, FTP server or mail server) behind the ZyXEL device assessable/visible to the outside world. A

Prestige 2302RL Support Notes

15
server behind the ZyXEL device cannot be set to be a DHCP client. That is, the server must use a fixed IP
address so outside users can access the server using the static IP address.
A service is identified by its standard port number. You can allow public access to servers for specified services
based on the port number. In addition, you can also set a default server behind SUA. Thus service requests that
do not match any of the servers are forwarded to the default server. If you do not set a default SUA server, then
the unknown service requests are simply discarded.
Configuration
To make a server visible to the outside world, specify the port number of the service and the inside address of
the server in 'Menu 15.2.1', Multiple Server Configuration. The outside users can access the local server using
the Prestige's WAN IP address which can be obtained from menu 24.1.
For example (Configuring an internal Web server for outside access) :

Configure a PPTP server Behind SUA
Introduction
PPTP is a tunneling protocol defined by the PPTP forum that allows PPP packets to be encapsulated within
Internet Protocol (IP) packets and forwarded over any IP network, including the Internet itself.
In order to run the Windows 9x PPTP client, you must be able to establish an IP connection with a tunnel server
such as the Windows NT Server 4.0 Remote Access Server.
Windows Dial-Up Networking uses the Internet standard Point-to-Point (PPP) to provide a secure, optimized
multiple-protocol network connection over dial-up telephone lines. All data sent over this connection can be
encrypted and compressed, and multiple network level protocols (TCP/IP, NetBEUI and IPX) can be run
correctly. Windows NT Domain Login level security is preserved even across the Internet.

Window98 PPTP Client / Internet / NT RAS Server Protocol Stack
PPTP appears as new modem type (Virtual Private Networking Adapter) that can be selected when setting up a
connection in the Dial-Up Networking folder. The VPN Adapter type does not appear elsewhere in the system.
Since PPTP encapsulates its data stream in the PPP protocol, VPN requires a second dial-up adapter. This
second dial-up adapter for VPN is added during the installation phase of the Upgrade in addition to the first
dial-up adapter that provides PPP support for the analog or ISDN modem.
The PPTP is already supported in Windows NT and Windows 98. For Windows 95, a software upgrade with
Dial-Up Networking 1.2 is required.
Configuration
This application note explains how to establish a PPTP connection to a remote private network on the Prestige
with SUA enabled. In ZyNOS, all PPTP packets are forwarded to the internal PPTP Server (Windows NT
server) behind SUA. . You must specify the PPTP port number in SMT menu 15 for the Prestige to forward
the packets to the intended Windows NT server using the private IP address.

Example
The following example shows how to dial to an ISP via the Prestige and then establish a tunnel to a private
network. You need to configure the settings on a PPTP server (such as a Windows NT server), a PPTP client
(Windows 9x) and the Prestige to set up the PPTP application. The following summarizes the setting for the
corresponding PPTP device.
oPPTP server setup (Windows NT)
Create a new VPN service in Control Panel>Network
Create a new PPTP user account
Enable the RAS port
Select a network protocol (such as IPX, TCP/IP or NetBEUI) for the RSA port
Set the Prestige as the Internet gateway
oPPTP client setup (Windows n9x)
In Dial-up Networking, create a secure VPN connection through the Prestige (using
the WAN IP address) and enter the correct user name and password to log into the
Windows NT RAS server.
Set the Prestige that connects to the ISP as the Internet gateway.
oPrestige Setup
Before establishing a VPN connection from the PPTP client (Windows 9x) to the PPTP server
(Windows NT server), you must first connect the Prestige to the ISP for Internet access.
Enter the IP address and the port number(s) of the PPTP server to allow public access to the server
behind the Prestige. The following shows a configuration example.

19
After you have set the settings to allow public access to the PPTP server, test the connection from the
PPTP client to the PPTP server. You can use Ping to check that the PPTP client can reach the PPTP
server over the Internet connection. For example, enter ‚ping 203.66.113.2‛ if the WAN IP address
of the Prestige is 203.66.113.2.
Once the connection is up, you can establish a secure VPN connection from the PPTP client to the ISP.
The default gateway is then used to route the traffic between the PPTP client and the server.
However, before you can establish a secure VPN connection from the PPTP client to the PPTP server,
you need to know the WAN IP address of the Prestige with the SUA feature enabled. Depending on
your Internet account type and ISP, the Prestige WAN IP address is either fixed(static) or dynamic
(different each time). You need to enter the WAN IP address of the Prestige in the VPN dial-up
connection screen. You can check the WAN IP address of the Prestige in SMT menu 24.1 or using PNC

Prestige 2302RL Support Notes

20
Monitor. If the Prestige is using a fixed (static) IP address, you can always use this fixed IP address to
connect to the PPTP server.
The following figure shows an example VPN dial-up screen. The VPN Server field is 140.113.1.225
which is a dynamic IP address assigned to the Prestige by the ISP. Make sure you enter the WAN IP
address of the Prestige correctly; otherwise, the VPN connection will fail. After the VPN connection is
established, you can start using Internet applications (such as on-line games).
Using NAT / Multi-NAT
What is Multi-NAT?
NAT (Network Address Translation-NAT RFC 1631) is the translation of an Internet Protocol address used
within one network to a different IP address known within another network. One network is designated the
inside network and the other is the outside . Typically, a company maps its local inside network addresses to one
or more global outside IP addresses and "unmaps" the global IP addresses on incoming packets back into local
IP addresses. The IP addresses for the NAT can be either fixed or dynamically assigned by the ISP. In addition,
you can designate servers, e.g., a web server and a telnet server, on your local network and make them
accessible to the outside world. If you do not define any servers, NAT offers the additional benefit of firewall
protection. In such case, all incoming connections to your network will be filtered out by the Prestige, thus
preventing intruders from probing your network.
