WatchGuard Technologies FireboxTM System 4.6 specification

Preparing the client computers

• Public IP address

Remote host operating system

The remote client must be running Windows and have the most recent MSDUN (Microsoft Dial-Up Networking) upgrades installed and may need other extensions and updates for proper configuration. Currently, Remote User VPN with PPTP requires these upgrades according to platform:

Encryption	Platform	Application
Both	Windows 95	DUN 1.3
Both	Windows 98	DUN 4.0
Base	Windows 98 SE	Second Edition
Strong	Windows 98 SE	DUN 128-bit
Base	Windows NT	40-bit SP4
Strong	Windows NT	128-bit SP4
Base	Windows 2000	40-bit SP4*
Strong	Windows 2000	128-bit SP4

*40-bit encryption is the default for Windows 2000. If you are upgrading from Windows 95 or 98, in which you had set strong encryption, Windows 2000 will automatically define strong encryption for the new installation.

Due to security concerns, RUVPN does not work with earlier versions of MSDUN.

If you install new software, you may have to reinstall the upgrades. The upgrades can be found at the Microsoft Download Center Web site at: http://www.microsoft.com/downloads/search.asp.

You may need the Windows installation CD to prepare the client computers.

Windows 95/98 platform preparation

Install the MSDUN upgrade on the remote client. The client is available free from Microsoft. For Windows 95, use DUN 1.3. For Windows 98, use DUN 4.0.

For 128-bit encryption, install the MSDUN upgrade 128-bit enhancement. This level of encryption is available for installations approved by WatchGuard and/or the U.S. government for strong encryption.

From the Windows Desktop:

1Select Start => Settings => Control Panel. Double-clickNetwork.

2Verify that Client for Microsoft Networks is installed.

If Client for Microsoft Networks is not installed, you must install it. For instructions, see “Installing Client for Microsoft Networks” on page 143.

3Click the Identification tab.

4Enter a name for the remote client.

This must be a unique name on the remote network.
