Thank you very much for your clarification.

In the project, connected to the switch next to the CP, the CP is configured without router, and both the IP of the CP as the laptop is assigned IP addresses that the client provides.
Indeed, when connected by VPN, the address automatically assigned by the client is the same as putting on laptop and the CP configured as without router.
These conditions are the conditions that have been connected to the VPN tunnel and has become a ping test to the direction of the COP and has given a positive result.
I do not know if it is correct that the CP is configured as without router, because when connected to the switch no problems of access, and connecting by VPN also does well the ping test.
While it is true that the TCP port 102 is not enabled.
