Technical Tip: Restrict FortiAuthenticator traffic to the Internet

Description

This article describes which ports and destinations FortiAuthenticator must use for communication with FortiGuard token services.

Scope

FortiAuthenticator 6.4.

Solution

FortiAuthenticator traffic can be restricted to the Internet, using only ports and destinations for the FortiGuard token services.

For mobile and hardware tokens (local, not via FortiToken Cloud):

- activation/registration soft token: fortitokenmobile.fortinet.com (443).

- activation/registration hard token: update.fortiguard.net (443).

- push notification proxy: push.fortinet.com (443).

- push response - incoming to whatever is configured in System Access.

- if sending activation tokens via FortiGuard SMS: msgctrl1.fortinet.com (443).

In addition, if FortiGate is serving as an edge firewall, it can be done with Fortinet Internet Services entries.

Policy & Objects -> Internet Service Database -> Fortinet.

Fortinet Internet Service Database can be added to the firewall policy and in that way restrict FortiAuthenticator traffic to the Internet.
