VPN Gateway 3050
7.0.1.0
The Nortel Networks VPN Gateway 3050 is a remote access
security solution that extends the reach of enterprise applications
and resources to remote users. The gateway performs on-the-fly
content transformation to instantly convert most intranet resour ces
into externally-viewable, secure HTML pages and employs an
advanced network address and port translation (NAPT) utility to
build SSL-secured VPN tunnels for client/server communications
Perimeter Defense (VPN, Firewalls & Intrusion Detection)
Solution Summary
The Nortel Networks VPN Gateway 3050 is a remote access security solution that extends the reach of
enterprise applications and resources to remote employees, partners, and customers. By using the
native capability of widely deployed Web browsers, the SSL VPN Gateway offers a convenient clientless
alternative for securely provisioning resources for remote users, without the need to install and manage
client tunneling software on their PCs.
Due to the clientless nature of this solution, Strong two factor authentication is essential to ensure the
identity of users connecting to your Enterprise from the internet. For this reason, Nortel Networks VPN
Gateway 3050 provides support for the RSA Authentication Manager as a method of strong
authentication for users using RSA SecurID Authentication.
For enterprises maintaining IPsec VPN environments, the Nortel VPN Gateway 3050 provides a new
level of deployment flexibility and end-user support by incorporating IPsec VPN client termination to
remove the network administrator's challenge of managing multiple devices to deliver both types of
remote access service.

Agent Host Configuration
Important: “Agent Host” and “Authentication Agent” are synonymous.
“Agent Host” is a term used with the RSA Authentication Manager 6.x
servers and below. RSA Authentication Manager 7.1 uses the term
“Authentication Agent”.
Important: All “Authentication Agent” types for 7.1 should be set to
“Standard Agent”.
To facilitate communication between the Nortel VPN Gateway and the RSA Authentication Manager /
RSA SecurID Appliance, an Agent Host record must be added to the RSA Authentication Manager
database and the RADIUS server database if using RADIUS. The Agent Host record identifies the
VPN Gateway
within its database and contains information about communication and encryption.
To create the Agent Host record, you will need the following information.
• Hostname
• IP Addresses for all network interfaces
When adding the Agent Host Record, you should configure the Nortel VPN Gateway as Communication
. This setting is used by the RSA Authentication Manager to determine how communication with
Server
Nortel VPN Gateway will occur.
the
To create the RADIUS client record, you will need the following information.
• Hostname
• IP Addresses for all network interfaces
• RADIUS Secret
Nortel
Note: Hostnames within the RSA Authentication Manager / RSA SecurID
Appliance must resolve to valid IP addresses on the local network.
Please refer to the appropriate RSA Security documentation for additional information about Creating,
Modifying and Managing Agent Host records.

Partner Authentication Agent Configuration
Before You Begin
This section provides instructions for integrating the partners’ product with RSA SecurID Auth entication.
This document is not intended to suggest optimum installations or configurations.
It is assumed that the reader has both working knowledge of all products involved, and the ability to
perform the tasks outlined in this section. Administrators should have access to the product
documentation for all products in order to install the required components.
All vendor products/components must be installed and working prior to the integration. Perf orm the
necessary tests to confirm that this is true before proceeding.

Known Issues
PIN Rejection: When a PIN is rejected by the Authentication Manager Server the user is questioned by
the client to try a different PIN but the program flow is not intuitive.
1. The user first authenticates using either Token or Password. The user is next prompted to create a new PIN.
2. The user must re-enter the new PIN to validate input from the previous step.
3. If rejected, the client displays the question to the user with an empty text box for input.
4. The client will accept any input by the user and then prompt for a new Passcode to restart the authentication
process.
5. The user then inputs a valid Passcode.
13
Administration Logon.
NEW-PIN mode does not work via the admin console. The user is prompted to create or accept a PIN
but the PIN never gets sent to the server and the user gets redirected to a blank web page.
