## About this task

Because the simulation environment is different for SA525M and SA515M, to make the
                TelAF SOME/IP Gateway service work properly in the simulation environment, users
                must follow the following steps to configure it based on their host
                environments.

## Procedure

1. Use the network tool (such as 'ifconfig') to get your real IP address for the
                    simulation container.
2. Fill the IP address to the 'unicast' field and the real interface name to the
                    'device' field of the JSON file:
                        /legato/systems/current/appsWriteable/tafSomeipGWSvc/tafSomeipGWSvc.json.
3. Restart the TelAF SOME/IP gateway service with `app start
                        tafSomeipGWSvc`.
                
Now the TelAF SOME/IP Gateway service should run properly.
