To configure the IAS Radius realm

Using RADIUS Servers for Authentication and Authorization

If you are already using SafeWord for Citrix or SafeWord RemoteAccess in your configuration to authen- ticate using the Web Interface, you need to do the following:

•Install and configure the SafeWord IAS Agent

•Configure the IAS RADIUS server to recognize the Firebox SSL VPN Gateway as a RADIUS client

•Configure the Firebox SSL VPN Gateway to send RADIUS authentication requests to the IAS RADIUS server

To install and configure the IAS Agent and the IAS RADIUS server, see the SafeWord for Citrix or SafeW- ord Remote Access product documentation.

If you are not currently using SafeWord for Citrix or SafeWord RemoteAccess, you should first install one of these servers following the product documentation.

To configure the Firebox SSL VPN Gateway to send RADIUS authentication requests to the IAS RADIUS server, follow the instructions in “Using RADIUS Servers for Authentication and Authorization” on page 69.

1Click the Authentication tab.

2In Realm Name, type a name for the authentication realm that you will create, select One Source, and then click Add.

3In Select Authentication Type, in Authentication Type, select RADIUS Authentication and click OK.

4On the Authentication tab, in Server IP Address, type the IAS RADIUS server IP address.

5In Server Port, type the IAS RADIUS server port. The default port numbers are 1812 and 1645.

6In Server Secret, type a RADIUS share secret.

Note

Make sure you use a strong shared secret. A strong shared secret is one that is at least eight characters and includes a combination of letters, numbers, and symbols.

7If there is a secondary IAS RADIUS server, configure the settings for the server in Secondary Radius

Server.

The RADIUS port number and the RADIUS server secret configured on the Firebox SSL VPN Gateway must match those configured on the IAS RADIUS server.

Using RADIUS Servers for Authentication and Authorization

You can configure the Firebox SSL VPN Gateway to authenticate user access with one or more RADIUS servers. For each RADIUS realm that you use for authentication, you can configure both primary and sec- ondary RADIUS servers. If the primary RADIUS server is unavailable, the Firebox SSL VPN Gateway attempts to authenticate against the secondary RADIUS server for that realm.

If a user is not located on the RADIUS servers or fails authentication, the Firebox SSL VPN Gateway checks the user against the user information stored locally on the Firebox SSL VPN Gateway if the Enable Local Database lookup check box is selected on the Settings tab of the realm.

The Firebox SSL VPN Gateway software also includes RADIUS authorization, which is configured using Remote Access Policy in Microsoft Internet Authentication Service (IAS). During configuration of the Firebox SSL VPN Gateway, the following information needs to be provided:

• Vendor ID is the vendor-specific code number that was entered in IAS.

This could involve mobile device verification or biometric authentication, significantly reducing the risk of unauthorized access.

Another key characteristic of WatchGuard’s SSL VPN is its integration with other WatchGuard security solutions. Businesses can benefit from a comprehensive security posture by leveraging firewalls and intrusion prevention systems along with the SSL VPN. This holistic approach ensures that remote connections are continually monitored and secured against evolving cyber threats.

Scalability is also a crucial aspect of WatchGuard's SSL VPN, accommodating growing organizations with changing needs.
