L2TPv3 can be regarded as being to MPLS what IP is to ATM: a simplified version of the same concept, with much of the same benefit achieved at a fraction of the effort, at the cost of losing some technical features considered less important in the market.
The process of setting up an L2TP/IPsec VPN is as follows: Negotiation of IPsec security association (SA), typically through Internet key exchange (IKE). This is carried out over UDP port 500, and commonly uses either a shared password (so-called "pre-shared keys"), public keys, or X.509 certificates on both ends, although other keying methods ...
www.tinc-vpn.org Tinc is an open-source , self-routing, mesh networking protocol and software implementation used for compressed and encrypted virtual private networks . It was started in 1998 by Guus Sliepen, Ivo Timmermans, and Wessel Dankers, and released as a GPL -licensed project.
SoftEther VPN Bridge is a VPN program for building a site-to-site VPN. [6] To build a site-to-site VPN network, the system administrator has to install SoftEther VPN Server on the central site, and has to install SoftEther VPN Bridge on one or more remote sites. A VPN Bridge connects to the central VPN Server by cascade connection.
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.
A Layer 2 MPLS VPN is a term in computer networking. It is a method that Internet service providers use to segregate their network for their customers, to allow them to transmit data over an IP network. This is often sold as a service to businesses. Layer 2 VPNs are a type of Virtual Private Network (VPN) that uses MPLS labels to
A strongSwan VPN client can act as a TNC client and a strongSwan VPN gateway as a Policy Enforcement Point (PEP) and optionally as a co-located TNC server. The following TCG interfaces are supported: IF-IMC 1.2, IF-IMV 1.2, IF-PEP 1.1, IF-TNCCS 1.1, IF-TNCCS 2.0 (RFC 5793 PB-TNC), IF-M 1.0 (RFC 5792 PA-TNC), and IF-MAP 2.0.
n2n is an open source Layer 2 over Layer 3 VPN app utilising peer-to-peer architecture for network membership and routing. Unlike many other VPN programs, n2n can also connect computers which reside behind NAT routers. These connections are set up with help from a third computer that both computers can reach.
