Introduction

This chapter describes the features of the NETGEAR ProSafe VPN Client. The NETGEAR ProSafe VPN Client is a remote access and end-point security product that

secures communications over the Internet and other public networks to create a virtual private network (VPN) between users. The NETGEAR VPN Client secures data communications sent from a desktop or portable computer across a public or private TCP/IP network. The client protects the office computer user and the home and mobile workforce.

The NETGEAR VPN Client supports secure client-to-gateway or client-to-client communications. For example, employees can telecommute from their homes to the office through the Internet or dial-in connections for secure client-to-gateway communications. Organizations that require a low-cost solution for secure communications among their employees or members across a private LAN, WAN, or individual dial-up connections can use the NETGEAR VPN Client for secure client-to-client communications.

The NETGEAR VPN Client starts automatically when the user's computer starts, and runs transparently at all times behind other software programs. A system tray icon indicates the status of communications for the client.

What's Included?

The NETGEAR ProSafe VPN Client contains two primary components:

• Security Policy Editor is where you create, import, and manage connections and their

associated proposals that make up your security policy.

• Certificate Manager allows users to request and retrieve, import, and store the certificates

users receive from certificate authorities (CAs), and to also set the trust policy.

There are also two diagnostic tools:

• Log Viewer lists the IKE negotiations that occur during Authenticatio n (Phase 1).

• Connection Monitor displays statistical and diagnostic information for each active

connection.

How to Configure a Security Policy

1. In the Security Policy Editor, in the Network Security Policy list, click the specific secure

connection .

2. In the Remote Party Identity and Addressing group, configure the remote party's information.

Note: When configuring security for L2TP, the remote party is the L2TP network server (LNS).

a. In the ID Type box at the top of the group, click one of these remote party identifiers:

• Domain name

• IP address

• Email address

• Distinguished name

•Any

b. In the IP Address box, type the IP address of the LNS. c. In the Protocol box, click UDP. d. In the Port box, click L2TP. e. Unless otherwis e instructed, make sure that the Connect using check box is clear.

3. Ask the remote party if you need to change the Port value to L2TP in My Identity.

4. When you configure the Key Exchange (Phase 2) proposal, in the Encapsulation box, click

Transport, which is the typical L2TP connection setting.

5. Click Save.

When Using a Modem to Establish the L2TP Connection

Note: If you use a network or broadband connection, such as cable or DSL, to establish an L2TP connection on a network, skip this topic; it doesn't apply. If you have questions, contact your network security administrator.

If you establish the L2TP connection from your computer through a physical di al-up connectio n— that is, a modem—your computer requires two Microsoft dial-up connections or adapters:

• One for the L2TP connection, which is a virtual connection

Reference Manual for the NETGEAR ProSafe VPN Client

• One for the physical dial-up connection

Therefore, you must add another dial-up connection through Windows. The specific steps required to add a second dial-up connection differ among the various Windows operating systems. This is the general procedure:

1. On your computer, in Windows help, look up network adapters, network connections, or

add a connection.

2. In Control Panel, open the Network or Network and Dial-up Connections application.

3. Follow the instructions in the help to add another dial-up connection or adapter.

Note: In Windows 95 and 98, dial-up adapters may be labeled Dial-Up Adapter and Dial-Up Adapter#2 (VPN Support).

If you need additional help, contact your network security administrator or IT staff.

Chapter 5

Using the Security Policy Editor

This chapter describes how to use the Security Policy Editor of the NETGEAR VPN Client.

What is the Security Policy Editor?

The Security Policy Editor is the client module in which you (or your network security administrator) create, import, and export security policies. Only one security policy is in effect at any time.

The policy contains connections and proposals that define the address of the remote (or other) party, the security level for the connection, how you identify yourself to the other party, and other attributes concerning the proposals and connections.

The sequence of the connections in the Network Security Policy list in the Security Policy Editor determines the order in which the client tests for a match between an incoming transmission and the proposed policies, and in turn defines the connection's security policy.

There are two ways to open the Security Policy Editor:

• On the Windows desktop, click Start>Programs>NETGEAR ProSafe VPN Client>Security Policy Editor.

• Right-click the NETGEAR ProSafe VPN Cl ient icon>Security Policy Editor.

Basic Steps to Configure a Security Policy

Caution: Before attempting to configure the security policy, check with your network security administrator: your security policy may have been configured when the client was installed.

Table 5-1. Summary of steps

Step Task

1 • Create one connection that secures all communications, with the option to direct all

connections to a specific gateway

• Create multiple connections and specify which ones to secure 2 Select options that apply to all connections in the security policy 3 Identify yourself (the user) through one of these methods:

Select the personal certificate Let the client automatically select the personal certificate du ring IKE negotiation Enter the specific preshared key

4 Select the Phase 1 mode:

Main Mode (high security) Aggressive Mode (low security) Manual keys (for troubleshooting only)

5 Add proposals, if needed, and select these options:

Encryption algorithm Hash algorithm SA life Key (Diffie-Hellman) group

6 Add proposals, if needed, and select the options for Encapsulated Security Payload (ESP)

or Authentication header (AH) 7 Identify backup gateways on the network 8 For network administrators or installers only: Create and deploy a customized client

installation package, with the security policy you configured, to users

How to Secure All Connections

You can create a single connection called All Connections in your security policy that secures all IP communications between your computer and every other party.

1. In the Security Policy Editor, click Options>Secure>All Connections . A secure connection

called All Connections is added to the Network Security Policy list.

2. To route all secure communications from your computer through a specific , secure,

IPSec-compliant network gateway, such as a firewall or router, go to Configure a gateway.

3. Click Save.

5-2 Using the Security Policy Editor

Configure My Identity for this connection.

5. Exit the Security Policy Editor.

How to Configure Global Policy Settings

Global policy settings are program preferences that apply to all secure IP communications. You can change these at any time to match to your security policy.

1. In the Security Policy Editor, click Options, and then click Global Policy Settings. The

Global Policy Settings dialog box opens.

2. In the Retransmit Interval box, type the length of time, in seconds, that the client waits

before resending an IKE protocol packet that has not been responded to. The de fault is 8 seconds.

Note: If the client selects a redundant gateway when you know that the primary one is available, try entering a higher number for Retransmit Interval.

3. In the Number of retries box, type the number of times your computer resends an IKE

protocol packet before abandoning the exchange. The default is 3 tries.

4. Status notifications are messages that inform communicating parties what the time-out periods

are and whether their security proposals have been accepted or rejected. To send thes e messages, select the Send status notifications to peer host check box.

5. An internal network IP address is a virtual IP address assigned to the client user. Remote users

can appear as internal users on a private network to, for example, access a WINS server or browse the network.

To enable remote users to appear as internal users on a private network, select the Allow to Specify Internal Network Address check box.

Note: If you select this check box, you must enter a private internal network IP address when Configuring My Identity.

6. To enable logging the Log Viewer's IKE negotiation messages to the isakmp.log file in the

client's installation directory , select the Enable logging to a file check box. This can facilitate remote troubleshooting by allowing a user to send a file with these messages instead of repeatedly freezing and printing the Log Viewer.

Notes:

Using the Security Policy Editor 5-3

202-10015-01

Reference Manual for the NETGEAR ProSafe VPN Client

• The maximum size for the isakmp.log file is 100 KB. When the client computer, the client, and the IKE service restart and the isakmp.log file size exceeds 100 KB, this isakmp.log file is deleted and a new one created.

• On computers running Windows 95 and 98 , when the isakmp.log file size exceeds 64 KB, Notepad prompts the user to try WordPad instead because of the file's size. When the user tries WordPad, however, WordPad prompts the user that it can't open the file because it is in use by another program (the IKE service).

In this case, to view the file, try one of these options: – Rename it, and then open it in WordPad. – Open a read-only version of the file in Microsoft Word. – Clear the Enable logging to a file check box, and then open the file.

7. If you don't use a smart card and reader or similar device to authenticate your identity, skip this

step. If you do use a smart card and reader or similar device, the client can, when it detects that the

smart card or reader is removed, delete active keys and end these communications sessions. This provides extra security. Only connections that use the keys on your smart card are affected.

To enable this feature, select the Smart card removal clea rs key s ch ec k box.

8. Click OK.

9. Click Save.

How to Configure Other Connections

The security policy includes a connection called Other Connections. This connection, non-secure by default, is designed to allow all non-encrypted IP traffic through and let you to access the Internet and other public networks unsecured.

The client processes connections in the order in which they display in the Network Security Policy list. Because Other Connections is the catchall or default rule for communications that don't conform to the proposals for individual connections, it is always last in the connections list.

1. In the Security Policy Editor, click Options, point to Secure, and then click Specified

Connections.

2. In the Network Security Policy list, click Other Connections.
