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
/27 255.255.255.224 30
/26 255.255.255.192 62
/25 255.255.255.128 126
/24 255.255.255.0 254
/23 255.255.254.0 510
/22 255.255.252.0 1022

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.
