L2TP VPN
Layer 2 Tunneling Protocol (L2TP) is a tunneling protocol used to support virtual private networks (VPNs) or as part of internet service delivery. It operates by encapsulating Layer 2 frames, such as PPP, over an IP network to create a secure tunnel between endpoints, enabling the transmission of non-IP protocols across IP-based infrastructure. This technology allows for the establishment of a point‑to‑point connection over a public network, where encapsulation and decapsulation are performed at the tunnel endpoints to maintain data integrity and session continuity

|
Field |
Description |
|
Specify the interface to establish L2TP tunnel. Only specified interface turn into active WAN will start VPN tunnel. Default is null and unbound link interface. e.g. WAN, WWAN1, etc.. |
|
L2TP over IPsec is a VPN technology that operates by encapsulating the L2TP protocol within the IPsec protocol. |
| Enable NAT | Enable: The source address of the data packets flowing out from the lower host device is NAT-ed to the VPN virtual IP. |
