Integrated VPN
For the Scout Cloud Gateway, OpenVPN is operated in routing mode (TUN device). This operating mode is recommended as the more efficient method: The VPN operates in layer 3 carrying only IP packets, which reduces bandwidth load.
For each connected device, one IP address is required (subnet topology).
For a given number of devices to be managed, determine the required subnet mask that filters your IP address (VPN range). In Configuration > Gateways, for your instance, enter the subnet mask in dotted decimal notation.
Examples:
| Subnet mask/CIDR | Subnet mask/dot-decimal | Max. number IP addresses |
|---|---|---|

255.255.255.224 |

The maximum number of available IP addresses corresponds to the maximum number of devices that can be connected.
The device manages the leases itself and acts like a miniature DHCP server. One lease is valid for 10 minutes.
