FortiGate: Admin GUI mit Chrome Browser on Mac nicht erreichbar

Mit iOS 13 und macOS 10.15 (Catalina) hat Apple die Schraube bei den TLS Zertifikaten angezogen:

Dies führt dazu, dass bei frisch aufgesetzten FortiGates das Admin GUI per Chrome Browser nicht mehr erreichbar ist. Als Fehlermeldung wird NET::ERR_CERT_REVOKED angezeigt.

Verantwortlich ist folgende Richtlinie: TLS server certificates [issued after July 1, 2019] must have a validity period of 825 days or fewer.

Um das Problem permanent zu lösen, braucht es ein SSL Zertifikat, welches den neuen Apple Richtlinien entspricht (Gültigkeit <= 825 Tage). Das Zertifikat fürs Admin GUI wird unter System > Settings konfiguriert.

Als Workaround kann man in Chrome auf der Fehlerseite den Text thisisunsafe eintippen.

OneSpan Authentication Server Appliance 3.19 Upgrade Issue

Official information from OneSpan published on January 10, 2020:

We have discovered an issue when upgrading OneSpan Authentication Server Appliance from version 3.18.x to 3.19. The upgrade brings the appliance in a non-operational state.

The Authentication Server Appliance and Authentication Server Virtual Appliance offline upgrade packages have been taken offline on January 9th. The online upgrade process to version 3.19 has also been disabled.

If you have a local copy of the version 3.19 offline upgrade package, do NOT use it to upgrade from 3.18.x to 3.19.

The issue does not occur when you perform a fresh installation of Authentication Server Virtual Appliance version 3.19 and the installation files can still be downloaded.

We are working on a solution for this problem and will make the version 3.19.1 available as soon as possible. We estimate version 3.19.1 will be available in week 4 (Week of January 20th).

FortiClient VPN 6.2

Mit dem Release von FortiClient 6.2 wurde der bisherige Full Featured FortiClient lizenzpflichtig und setzt einen FortiClient EMS Server voraus. Im Gegenzug hat Fortinet einen separaten VPN-only Client veröffentlicht. Fortinet beschreibt den FortiClient VPN folgendermassen:

For FortiGate administrators, a free version of FortiClient VPN is available which supports basic IPsec and SSL VPN and does not require registration with EMS. This version does not include central management, technical support, or some advanced features.

Basic IPsec and SSL VPN bedeutet in diesem Zusammenhang, dass folgende Features nicht enthalten sind:

  • IKEv2 support
  • VPN auto-connect/always-up
  • on-net/off-net
  • host check features
  • Central management

Ebenfalls gibt es für die Version 6.2 kein FortiClient Configuration Tool . Um benutzerdefinierte Installationspakete zu erstellen, wird zwingend ein FortiClient EMS Server benötigt.

Der FortiClient VPN ist unter erhältlich. Weitere Informationen dazu gibt es im KB Limitation and features on Forticlient.

FortiOS 6.2: Upgrade Notes

As with every software product, even the latest and greatest releases have some known glitches. That’s one of the reasons why you should review the release notes as part of the upgrade process.

But even then you might face a not-yet-documented issue. You’ll find some notable examples below.

FortiAPs won’t connect anymore (6.2.1)

Some customers have reported, that their FortiAPs won’t connect anymore after upgrading to FortiOS 6.2.1. Fortinet has confirmed that this is a know issue only when using trusted hosts to restrict the administrative access to the FortiGate.

The official workaround is to add the FortiAP’s IP or subnet as an additional trusted host entry on one of the admin users:

config system admin 
   edit "adminuser"
     set trusthostx <-- IP Address of the FortiAP

RADIUS Server behind VPN-Tunnel not working (6.2.1)

When using a RADIUS server behind an IPsec-tunnel, you most likely had to configure the source-ip in the radius configuration (normally to the internal address of the firewall). A bug in FortiOS 6.2.1 prevents this from working. As a workaround you’ll have to use an ip address owned by the outgoing interface.

config user radius
  edit "nps-server"
    set source-ip "" <-- IP Address of the outgoing (IPsec)interface

What’s new with FortiOS 6.2: Update issue with certificate for WebUI

Recently we have had a few support cases where a customer was unable to log in to the firewall via WebUI after the firmware update. But SSH access worked fine.

It turned out that during the update process the server certificate used for the WebUI is lost.

Config with v6.0.4 (it does not happen with „self-signed“ only):

config system global
set admin-server-cert "self-signed"
