FortiGate SSLVPN Update-Empfehlung

Update, Nov 2020:

More than a year after Fortinet described this SSLVPN vulnerability, it gets new attention. A few days ago a list of IPs and domain names of vulnerable Fortigates was published. This list is dated November 2019 and one can only hope that many of these systems have already been patched.

Two days ago, this list was extended with usernames and passwords that were exploted via this vulnerability. Even if the Fortigates have been patched – as long as the passwords have not been changed, an attacker could still use them to gain access to protected networks.

FortiGate: Deny-Policies for SD-WAN members

SD-WAN is a cool feature to configure redundant internet access. But it was designed with load-balancing in mind and this brings some challenges to specific use cases. As an example, while you can use SD-WAN rules to define the preferred path for a specific application/system, it won’t prevent that the traffic is routed over another interface in case of an outage.

CheatSheet – FortiOS v6.4

The System Engineers of BOLL Engineering have been supporting Fortigate devices for 18 years. This year, FortiOS v6.4 was released and we have again gathered all the troubleshooting commands that we use regularly in our new CheatSheet.

Hopefully this CheatSheet will help you as well.

You will find the most important commands on the first page. The second page contains troubleshooting commands for problems with firewall policies and security profiles, followed by the third page with commands for network problems. The last page covers system and hardware commands and general information.

Updated to v1.1 (addition and correction for FortiToken, 11.12.2020)

Happy troubleshooting!

Fortigate VM Azure: IPsec performance issue

Based on two recent support cases regarding the IPsec performance between an OnPrem and Azure FortiGate, we did some testing using the latest FortiOS 6.4.1.

We’ve created a basic IPsec tunnel using the wizard, deployed an Ubuntu machine at both sites and used iPerf3 to do some speed testing. The results were nowhere near the expected numbers, while sending from Azure to OnPrem (~250Mbit/s) was a bit faster than reverse (~120Mbit/s).

FortiClient VPN: Download Mirror

Da die Server von www.forticlient.com gut ausgelastet waren zu beginn der Homeoffice-Zeit wegen COVID-19, haben wir unseren Resellern hier während dieser Zeit den Download des FortiClients über unsere Server ermöglicht. Dies ist unterdessen nicht mehr notwendig und daher haben wir die Links wieder entfernt. Wir Verweisen auf www.forticlient.com.

Fortinet hat übrigens aufgrund der grossen Supportanfrage zum Thema eine eigene Seite für Home-Office/Remote-Office Thematiken erstellt. Darauf sind viele Anleitungen und Videos zum Thema zu finden. Der Artikel ist hier zu finden.
