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)
There seems to be a vulnerarbility in some FortiMail versions, that allow an unauthenticated remote attacker to access the system by requesting a password change. Please refer to the FortiGuard PSIRT article.
The problem here is not only the unauthorized access to the system, but also the change of the password of all configured administrative accounts. Also, the maintainer functionality to reset the administrator password over a serial console of the FortiMail is being disabled from the attacker.
Since June 1st you may notice that some websites (https) are not working anymore when Fortigate or the Palo Alto Networks Firewall is doing decryption or certificate inspection. Typically you are getting one of the following error messages:
Because it’s very difficult to take exams at PearsonVUE right now, you may get in trouble regarding the timely recertification of existing certifications. Therefore some vendors have announced an extension for their recertification expiration:
PaloAltoNetworks is extending the certification expiration date by six month for Credential holders with expiration date between March 1, 2020 and July 31, 2020.
Fortinet is extending the certification expiration by one month so far. We assume that this extension will be extended again :-). Update March 27th: Fortinet will extend the expiry dates of all existing NSE certifications by 6 months as of March 16th 2020 (the date of PV’s test center closures).
FortiOS v6.2 has been released in March this year and we are still gaining experience with this version. In this article we would like to draw you attention to the protocol which is used for FortiGuard service communication. Up to v6.0 udp has been used, with 6.2 the default protocol has changed to https.
