I do not think there's an explicit support for selecting a network interface to connect from in JSch.

But you can implement a SocketFactory interface, such as that it creates a Socket instance using the constructor overload with the localAddr:

public Socket(InetAddress address, int port, InetAddress localAddr, int localPort)

(use 0 for the localPort)

Then pass the factory to the Session.setSocketFactory() before calling the connect() and you should be good.
