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 ...
IPsec can protect data flows between a pair of hosts (host-to-host), between a pair of security gateways (network-to-network), or between a security gateway and a host (network-to-host). [1] IPsec uses cryptographic security services to protect communications over Internet Protocol (IP) networks.
Fortinet FortiGate and; Array Networks AG SSL VPN (since 8.20) [6] It was originally written as an open-source replacement for Cisco's proprietary AnyConnect SSL VPN client, [7] which is supported by several Cisco routers. As of July 2023, support for several other proprietary VPN protocols is desired or in development:
Virtual private network (VPN) is a network architecture for virtually extending a private network (i.e. any computer network which is not the public Internet) across one or multiple other networks which are either untrusted (as they are not controlled by the entity aiming to implement the VPN) or need to be isolated (thus making the lower network invisible or not directly usable).

IPsec VPN configurations which allow for negotiation of multiple configurations are subject to MITM-based downgrade attacks between the offered configurations, with both IKEv1 and IKEv2. [23] This can be avoided by careful segregation of client systems onto multiple service access points with stricter configurations.
Split tunneling is a computer networking concept which allows a user to access dissimilar security domains like a public network (e.g., the Internet) and a local area network or wide area network at the same time, using the same or different network connections.
Fortinet introduced its first product, FortiGate, in 2002, followed by anti-spam and anti-virus software. [ 5 ] [ 6 ] The company raised $13 million in private funding from 2000 to early 2003. [ 5 ] Fortinet's first channel program was established in October 2003.
