Create RADIUS or TACACS+ Authentication Server elements

You can authenticate end-user access through Firewalls and administrator’s logons to the SMC against external authentication servers that support either the RADIUS or TACACS+ protocol.

RADIUS servers support both IPv4 and IPv6 addresses.

User authentication is only supported for IPv4 traffic.
Authentication of administrator logons is supported for both IPv4 and IPv6 traffic.

TACACS+ servers only support IPv4 addresses.

For more details about the product and how to configure features, click Help or press F1.

Steps

Select Configuration, then browse to User Authentication.
Right-click Servers and select New > RADIUS Authentication Server or New > TACACS+ Authentication Server.
Configure the settings on the General tab.
(Optional) Click the Secondary IP Addresses tab and add more IP addresses.
These IP addresses are only used in Access rules and routing. Firewalls always use the main IP address of the RADIUS or TACACS+ authentication server when they contact the authentication server.
(Optional) If you want the RADIUS or TACACS+ authentication server to be monitored by the Log Server, click the Monitoring tab and configure the monitoring settings.
Click OK.
Configure the RADIUS or TACACS+ authentication server to accept connections from your Firewall engines:
- Make sure that the shared secret is entered identically in the Management Client and on the RADIUS or TACACS+ authentication server.
- The identity that the Firewall provides to the server is the IP address of the interface that has been selected as the value for the Identity for Authentication Requests in the Firewall’s Interface Options.
  Note: The IP address used as the identity is a name only. The interface and IP address used for the authentication-related connections is selected based on the Firewall’s routing information just like for any other connection.

Result

The connections to RADIUS or TACACS+ authentication servers are allowed in the predefined Firewall Template. Make sure your IPv4 Access and IPv4 NAT rules for user authentication are configured correctly for these connections.

RADIUS Authentication Server Properties dialog box

Use this dialog box to define RADIUS Authentication Server properties.

Option	Definition
General tab
Name	The name of the element.
IP Address	The IPv4 or IPv6 address of the server. Note: You can only enter one IP address.
Resolve	Automatically resolves the IP address of the server from a domain name in the Name field.
Location	Specifies the location for the server if there is a NAT device between the server and other SMC components.
Contact Addresses	Default — Used by default whenever a component that belongs to another Location connects to this server. Exceptions — Opens the Exceptions dialog box.
Port (Optional)	Specifies the port number if the server communicates on a port other than the default port. The predefined Firewall Template allows the engines to connect to the default port. If you change to a custom port, you must add a IPv4 Access rule to allow the traffic.
Shared Secret	Specifies the secret key for communication with the RADIUS authentication server.
Hide	Deselect to see the text as you type.
Number of Retries	Specifies the number of times Firewalls try to connect to the RADIUS authentication server if the connection fails.
Timeout	Specifies the time (in seconds) that Firewalls wait for the RADIUS authentication server to reply.
Category (Optional)	Includes the element in predefined categories. Click Select to select a category.
Tools Profile	Adds custom commands to the server right-click menu. Click Select to select a Tools Profile element.
Comment (Optional)	A comment for your own reference.
