Layer 2 Tunneling Protocol. In computer networking, Layer 2 Tunneling Protocol ( L2TP) is a tunneling protocol used to support virtual private networks (VPNs) or as part of the delivery of services by ISPs. It uses encryption ('hiding') only for its own control messages (using an optional pre-shared secret), and does not provide any encryption ...
This is a list of the IP protocol numbers found in the field Protocol of the IPv4 header and the Next Header field of the IPv6 header. It is an identifier for the encapsulated protocol and determines the layout of the data that immediately follows the header.
OpenConnect. OpenConnect is a free and open-source cross-platform multi-protocol virtual private network (VPN) client software which implement secure point-to-point connections. The OpenConnect client supports the following VPN protocols: It was originally written as an open-source replacement for Cisco 's proprietary AnyConnect SSL VPN client ...
Tunnels. PPP. MAC. more... v. t. e. In computing, Internet Protocol Security ( IPsec) is a secure network protocol suite that authenticates and encrypts packets of data to provide secure encrypted communication between two computers over an Internet Protocol network. It is used in virtual private networks (VPNs).
The port numbers in the range from 0 to 1023 (0 to 2 10 − 1) are the well-known ports or system ports. They are used by system processes that provide widely used types of network services. On Unix-like operating systems, a process must execute with superuser privileges to be able to bind a network socket to an IP address using one of the well ...
IP tunnel. An IP tunnel is an Internet Protocol (IP) network communications channel between two networks. It is used to transport another network protocol by encapsulation of its packets . IP tunnels are often used for connecting two disjoint IP networks that don't have a native routing path to each other, via an underlying routable protocol ...
In the case of a tunnel broker using TSP, the client automatically restarting the tunnel will cause the endpoint address and port to be updated. Implementations. The first implementation of an IPv6 Tunnel Broker was at the Italian CSELT S.p.A. by Ivano Guardini, the author of RFC 3053 [failed verification]
