Description

This article describes how to change the TLS version for the incoming listening port TCP/8888, TCP/8890, TCP/8891 and TCP/8900 in FortiManager and FortiAnalyzer (if applicable).

 

TCP/8888 : For FortiGate Web Filter queries, AV & IPS updates.

TCP/8890 : For FortiGate Registration for license validation and UTM updates (AV, IPS).

TCP/8891 : FortiManager listens to FortiGuard for FortiClient AV/IPS database and Web Filter database updates.

Scope  
Solution

By default all the said listening ports are set to TLSv1.2, to change to different TLS version for those ports, it is possible set via CLI as follows, example below was based on version 7.0.

 

# config fmupdate fds-settin
  set fds-ssl-protocol <version>
   sslv3 set SSLv3 as the lowest version.
   tlsv1.0 set TLSv1.0 as the lowest version.
   tlsv1.1 set TLSv1.1 as the lowest version.
   tlsv1.2 set TLSv1.2 as the lowest version (default).
   tlsv1.3 set TLSv1.3 as the lowest version. 

end

 

Note.

fds-ssl-protocol - The SSL protocols version for receiving FortiGate connection (default = tlsv1.2).
