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.

To connect the device to the provider network, you should request the network settings from the
provider. If you use 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.

phone network for all subscribers. You may specify IP address as well as the domain name (specify
an alternative SIP server UDP port after the colon, default value is 5060)
Registration
– when selected, subscriber port registration will be enabled on the registration
server;
Registration server
– network address of a device that is used for registration of all phone network
subscribers in order to provide them with the communication services (specify an alternative
registration server port after the colon, default value is 5060). You may specify IP address as well
as the domain name. Usually, registration server is physically co-located with SIP proxy server
(they have the same address);
SIP domain
– domain where the device is located (fill in, if required), is assigned automatically
when receiving DHCP option 15 or specified manually. A manually specified domain takes
precedence over the DHCP configuration.
