I`m new here and need help to create List of applications and protocols their use for external communications on our Fortigate devices (Fortigate 900D) including the application which use „tunneled protocols". The reason is, we`re using proxy device for „external communications“. On that device we have enabled functionality „bypass unknowns protocols“. We want to disable this options, but before that we would like to find out what type off applications/ports using functionality „unknown protocols“. Very good example is TeamViewer applicaiton. Teamviewer by default uses port 5938. Our proxy evaluates this connections like „unknown protocol“, and allowed/pass this communications, but our Fortigate device blocked this communications because is on „blacklisted list“. However TV hide (use tunneled protocol functionality) under HTTPS and both devices (proxy and Fortigate (Fortigate NEVER analyse incoming communications from our proxy devices/header inspections)) allowed this communications.
