The FIX Adapter does not support SSL natively. You can use an SSL wrapper to wrap the FIX server connection inside SSL. For example, Stunnel (www.stunnel.org). The setup will be something like the following:

For example, if the remote server is running on remotehost:443, then in the stunnel configuration file on localhost the following configuration is needed:

Then in the FIX Adapter configuration file, for the transport property QuickFIX.SocketConnectHost the value should be "localhost", and for property QuickFIX.SocketConnectPort the value should be "12345".
