| | 10 | <li>adding a route in your default gateway for the VPN network IP subnet pointing to the OpenVPN machine,</li> |
| | 11 | <li>adding a route to every client, or</li> |
| | 12 | <li>NATing all VPN traffic to the local address of the OpenVPN machine for network traffic which leaves the OpenVPN machine for the local net.</li> |
| | 13 | </ul> |
| | 14 | </li> |
