Tunneling Tab

Secure XDMCP sessions or Xstart SSH protocol sessions utilize X11 forwarding (TCP/IP forwarding using the SSH protocol) to use X applications. User can also use general forwarding (SSH tunneling) and can list, add, edit, and remove SSH tunneling channels registered in the session.

List Box
This area list the TCP/IP forwarding rules stored I nthe current sessoin file.

Add
Users can add a new TCP/IP forwarding rule.

Type(Direction):

• When using Local Forwarding, the connection through the local PC's listening port is forwarded to a specific port of the destination host.

• When using Remote Forwarding, the connection through the remote host's listening port is forwarded to a specific port of the destination host.

• Dynamic Forwarding works in the same way as Local Forwarding except the destination host is not specified. For reference, Dynamic Forwarding uses the SOCKS protocol with a default port number of 1080.

Source Host: This is the host to receive packets during forwarding. If the using Locol Forwarding, users can generally enter localhost here. If an IP address is entered, it can be set seperately for each network device.

Listening Port: This is the port number of the host to receive packets during forwarding. If an IP address was entered as the source host, this can be set separately for each network device.

Accept local connections only: If this option is turned on, access to the specified port will be blocked for other PCs or hosts. Only the locally requested forwarding will be processed.

Destination Host: Enter the host name or ip address where the arrived packets at the source port of the source host will be forwarded.

Destination Port: This is the port number of the destination host to which arriving packets at the source port of the source host will be forwarded.

Description: Enter a description of this forwarding rule.
