Product Name VPN Gateway 3050
Version & Platform 7.0.1.0
Product Description 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 resources
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
Product Category 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 Nortel
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
Server. This setting is used by the RSA Authentication Manager to determine how communication with
the Nortel VPN Gateway will occur.
To create the RADIUS client record, you will need the following information.
•Hostname
•IP Addresses for all network interfaces
•RADIUS Secret
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 Authentication.
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. Perform the
necessary tests to confirm that this is true before proceeding.
Nortel VPN Gateway 3050 Agent configuration
Administrative tasks can be performed in the Command Line Interface (CLI) as well as the Web
Administration GUI. All configuration steps and screenshots in this guide will refer to GUI administration.
Please refer to Nortel Administrative documentation for more complete details on CLI and GUI
Administration tasks.
RSA SecurID Authentication Configuration Overview
1. Create a User Group
2. Configure the RSA Server record
3. Configuring the RSA SecurID Authentication Servers
RADIUS Authentication Configuration Overview
1. Create a User Group
2. Configuring the RADIUS Authentication Servers
5

Creating and Configuring a RSA SecurID or RADIUS User Group
1. From the admin console, expand VPN Gateways and click Add to add a VPN Gateway.
2. Click
Create VPN.
3. Now click on the VPN Gateway you just created and click on Groups.
4. Click on the button Add New Group.
5. Fill out the form with the desired group name, user type and description.
6. Click Update and then Apply to add the new group to the configuration.
7. From the Groups menu on the administration console, click on the group name.
8. Select the Access List tab.
9. Create an appropriate Access list based on your organizations configuration. In the example below you will
see we have created a generic rule allowing all access for authenticated RSA SecurID or RADIUS users.
10. Click Update to apply the Access rules.
11. Configure the user group for any necessary links or VPN Settings as required.
12. Click Apply to add the new information to the IOS configuration.

Configure the RSA Server record
1. Open the Management Interface (MIP) of the Nortel VPN Gateway using a web browser. Authenticate with
administrative user account and select the Config tab.
2. From the SSL-VPN admin menu select Administration > RSA Servers item.
3. Click the Add button and complete the form.
4. Click Apply to commit changes to the IOS configuration.

Note: The user name does not need to exist on the VPN Gateway 3050
in order to be authenticated. The VPN Gateway 3050 will pass off
authentication to the RSA Authentication Manager as a trusted
authentication source.
