In the Connection section, you can modify the following connection settings:
Connection mode. In this menu, you can edit the connection mode:
Gateway. This mode is ideal for Terminal servers, VDI desktops and remote PCs that are only reachable via Parallels Secure Gateway.
Direct. Parallels Client connects directly to the remote server. This option can be used when both Parallels Client and the server are connected to the same network.
Secure connection. This option defines whether Parallels Client is using an SSL certificate to establish a connection to Parallels Secure Gateway. You should change this setting only if your system administrator told you to do so.
Port. In this field, you can modify the port. You should do this only if your system administrator told you to do so.
Secondary connections. If the server you are connecting to has more than one RAS Secure Gateway, you can define a secondary connection, which will be used as a backup connection in case the primary connection fails. To add a secondary connection, tap this field, tap the + icon in the top right corner and do the following:
Specify a server name or IP address. This should be a server hosting a secondary RAS Secure Gateway (the primary gateway is used by the primary connection).
Select the connection mode and modify the port number if necessary. Tap OK.
Back in the Secondary Connections dialog, you can move connections up or down the list if you have more than one. If the primary connection cannot be established, Parallels Client will use secondary connections in the order listed.
Server authentication. Tap this field to choose what to do when an untrusted certificate is used to establish connection to the remote server.
Proxy. If you have to use a proxy server to connect to Parallels Remote Application Server, tap this field and specify the proxy server parameters.
Connection timeout. Specify the time interval (in seconds) after which Parallels Client should stop trying to connect to RAS if it failed to connect at once.
Reconnect if connection is dropped. Parallels Client tries to reconnect if the connection was dropped.
Multi-factor authentication. When you log in to Parallels RAS via MFA, specifically of type RADIUS, the OTP dialog is shown in Parallels Client with the actions icons positioned above the OTP field. You click an icon and the authentication is carried out according to the predefined action. For example, if you click the "Push" icon, a push notification is sent to your mobile device where you can simply tap "Approve". Or there could be a "Text me" icon, in which case a text is sent to your mobile phone with a one-time password.
If you always use the same authentication method, you can make it the default one. To do so, tap MFA authentication and select the Remember last method used checkbox.
