For example, this tries to connect with TLS 1.1, which the server negotiates to upgrade to 1.2: To forbid that the server upgrades the TLS version use the --tls-max option: In this case, the connection fails because the client does not offer any TLS version above 1.1, but the server does not accept any version below 1.2. WebEnter filter if your network uses IPv4. Adding EV Charger (100A) in secondary panel (100A) fed off main (200A). What is this brick with a round back and a stud on the side used for? Otherwise the connection will be terminated.Default Minimum and Maximum SSL/TLS Versions:#client means it is same with Client to FortiGate connection settingsv5.6:Client <-> FortiGate:Minimum Version: TLSv1.0Maximum Version: TLSv1.2FortiGate <-> Server:Minimum Version: client Maximum Version: clientv6.0:Client <-> FortiGate:Minimum Version: TLSv1.1Maximum Version: TLSv1.2FortiGate <-> Server:Minimum Version: client Maximum Version: clientv6.2:Client <-> FortiGate:Minimum Version: TLSv1.1Maximum Version: TLSv1.2FortiGate <-> Server:Minimum Version: client Maximum Version: clientDuring upgrade to v6.0 or v6.2, the default minimum version of SSL/TLS will change automatically to TLSv1.1. If used like this, the output is very similar to the openssl_client output. NET 4.5 defaults to TLS 1.1. ', referring to the nuclear power plant in Ignalina, mean? How to test which version of TLS my .NET client is using? The FortiGate will try to negotiate a connection using the configured version or higher. Indicates whether or not the entry is currently referred to by another item in the configuration.

Does anyone know (either on the FortiGate itself or on a workstation with FortiClient installed), how I can verify which version of TLS is being used and which cipher suite is being used to establish the VPN connection? If the internal server or a client does not support a SSL/TLS 1.1 or upper version, the connection will be terminated.
