We will get an additional tab through which we can install the applet. Install the applet and it will provide us with the local address along with the port number in order to telnet to the telnet server.

From our pc, telnet to 127.0.0.1:2323 and ASA1 will automatically redirect the request to telnet server.

CAPTURED PACKET:

The data is sent in encrypted format in the ssl tunnel (between ASA1 and external pc).

The data is sent in plaintext between ASA1 and internal server.
