Port Forwarding Settings

Outgoing

This describes outgoing connections from the local computer (that is, TCP connections that the local computer forwards from a specified local port to the specified port on the remote host computer). The display pane lists all outgoing port definitions you create. Use the buttons in this pane to add, edit, delete, copy, paste, and change the order of outgoing ports.

Incoming

This describes incoming connections to the local computer (that is, TCP connections that the remote host forwards from a specified remote port to the specified port on the local computer). The display pane lists all of the incoming port definitions you create. Use the buttons in this pane to add, edit, delete and change the order of incoming ports.

X11

These settings let you enable and configure X11 port forwarding. If you enable X11 port forwarding in a tunnel profile, when you start the tunnel, the Connectivity Secure Shell engine requests X forwarding upon connection to the Secure Shell server. If the server supports X forwarding, the Connectivity Secure Shell engine listens on the specified port.

You can also enable and disable X11 Authentication. When enabled, X11 authentication ensures that no other user account is permitted to open an X window on the Connectivity Secure Shell workstation. Advanced users may need to disable this option if, for example, they want to open an X window after they su (substitute user) to a different account.

Warning!
		If you su without a hyphen (-), the $DISPLAY variable is retained. (This variable is required to run an X11 command back to the PC.) If you su with a hyphen (-), then the $DISPLAY variable is not set. You will receive a "Can’t open display" message if you attempt to initiate a connection. You must set the $DISPLAY variable.
		In either case, if X11 authentication is enabled, the X window connection will fail.
