based on Point-to-Point Protocol (PPP) and act as its extension. First, the OSI model higher
level data is encapsulated into PPP, and then into PPTP or L2TP for tunnel transmission via
public data networks. PPTP and L2TP functionality differs. L2TP may be used not only in IP
networks, service messages for tunnel creation and data transfer use the same format and
protocols. PPTP may be used only in IP networks, it requires a dedicated TCP connection for
tunnel creation and usage. L2TP over IPSec

allows for the higher security level compared to
PPTP and provides the higher level of protection for business-critical data.
Due to its characteristics, L2TP is an attractive protocol for building virtual networks.
Bridge
– device operates in the bridge mode (switch with 5 ports). Set the following
parameters to get access:
–
IP
address
– bridge IP address;
–
Subnet mask
– subnet mask of bridge.

To connect the device to the provider network, you should request the network settings from the
provider. If you use the static settings, select 'Static' value in the 'Protocol' field and fill the 'External IP address',
'Subnet mask', 'Default gateway', 'Primary DNS', and 'Secondary DNS' fields with the corresponding values
obtained from the provider. If devices in the provider network obtain network settings via DHCP, PPPoE, PPTP,
or L2TP—select the corresponding protocol in the 'Protocol' field and refer to provider's instructions to achieve
complete and correct device configuration.
