7.2.1.2.2. Example of SSH Connection via NAPT

When you configure the connection to real network via the connect-real-network-napt command, it configures the service node to work as a gateway routing the outgoing traffic to the host PC (making available the host PC IP in the simulation environment). This can be used as an alternative to the create outgoing forwarding ports. In this case, you can directly use the IP from the host PC in the commands issued from the target system.

The following capture shows an example in which a SSH session is established. In this example, it is assumed that the NAPT configuration has been already performed. The host IP is 10.122.105.138.
