You can access a private network through the Internet by using a virtual private network (VPN) connection with the Layer Two Tunneling Protocol (L2TP). L2TP is an industry-standard Internet tunneling protocol.
Bridge Layer 2 Protocol Tunneling | Cumulus Linux 4.0 Layer 2 protocol tunneling is not a full-featured pseudo-wire solution; there is no end-to-end link status tracking or feedback. Layer 2 protocols typically run on a link local scope. Running the protocols through a tunnel across a layer 3 fabric incurs significantly higher … RFC 2661 - Layer Two Tunneling Protocol "L2TP" Abstract This document describes the Layer Two Tunneling Protocol (L2TP). STD 51, RFC 1661 specifies multi-protocol access via PPP [ RFC1661 ]. L2TP facilitates the tunneling of PPP packets across an intervening network in a way that is as transparent as possible to both end-users and applications.
The Layer 2 Tunneling protocol (L2TP) solves these issues by providing: A fairly comprehensive tunnel control protocol for the setup, teardown and maintenance of sessions RFC3931. Tunneling over UDP (RFC 3931 section 4.1.2) as well as IP. The UDP option allows for NAT traversal.

Layer 2 Tunneling Protocol : definition of Layer 2 History. Published in 1999 as proposed standard RFC 2661, L2TP has its origins primarily in two older tunneling protocols for Point-to-Point Protocol (PPP): Cisco's Layer 2 Forwarding Protocol (L2F) and USRobotics Point-to-Point Tunneling Protocol (PPTP). A new version of this protocol, L2TPv3, was published as proposed standard RFC 3931 in 2005. L2TPv3 provides additional security features
