This is the step-by-step procedure:
(1) Configure the following at the NAT device:
juniper@NAT# set security nat source rule-set nat1 rule r1 then source-nat pool mypool persistent-nat permit target-host
juniper@NAT# commit and-quit
(2) Next, start a telnet session from the HOST to the SERVER, and leave it open:
juniper@HOST> telnet 172.16.0.2
Connected to 172.16.0.2.
Escape character is '^]'.
Welcome to the cloud
password is Clouds
Don’t close the telnet session established above.
(3) At the NAT, execute:
juniper@NAT> show security flow session destination-prefix 172.16.0.2
The port numbers 60840 and 8330 are dynamic, so you will likely get different numbers in your case. Write down the second number or, in other words, the translated port number at the public side. In this example, it is 8330.
(4) Open another terminal and connect it to HOST, then launch:
