After an IPsec technology is assigned to a VPN topology, you cannot change the technology, other than by deleting the VPN topology and creating a new one. See Defining the Name and IPsec Technology of a VPN Topology, page 21-30. The following topics explain some basic concepts about IPsec technologies and site-to-site VPN policies:

How IPsec works, why we need it, and its biggest drawbacks The IP Security protocol, which includes encryption and authentication technologies, is a common element of VPNs (Virtual Private After an IPsec technology is assigned to a VPN topology, you cannot change the technology, other than by deleting the VPN topology and creating a new one.

Maybe it will save you and me time if one has to setup an IPsec VPN in the future. Hopefully it will ecourage other people to use Openwrt as an IPsec VPN router. We cannot provide a graphical user interface at the moment but at least it is a solid alternative to commercial IPsec appliances. In this VPN tutorial you will learn all about VPN basics, starting with the different types of VPNs and ending with a VPN implementation strategy. In the first section of the tutorial (below), learn the basics of IPsec and SSL VPNs and how they are deployed, or skip to other sections in the VPN tutorial using the table of contents below.

VPN Basics: Internet Protocol Security (IPSec) Internet Protocol Security (IPSec) is an Internet Engineering Task Force (IETF) standard suite of protocols that provides data authentication, integrity, and confidentiality when data is transferred between communication points across IP networks. IPSec provides data security at the IP packet level. SSL VPN and IPsec VPN: How they work - Calyptix

Once that has been set up and chosen, type your Pre-shared Key for the IPSec VPN, choose a subscription, a resource group and Click OK. Once this has completed, go to Virtual Network Gateways > your gateway > Connections and choose the connection we just made.

The basics of VPN encryption. VPN encryption scrambles the contents of your internet traffic in such a way that it can only be un-scrambled (decrypted) using the correct key. Outgoing data is encrypted before it leaves your device. It’s then sent to the VPN server, which decrypts the data with the appropriate key. VPN Connect (IPSec) • VPN Connect is a managed VPN service which securely connects on-premises network to OCI VCNthrough anIPSecVPNconnection • VPN Connect ensures secure remote connectivity via industry standard IPSecencryption • Bandwidth is dependent on the customer’s access to the Internet and general Internet congestion (Typically less Site-to-Site IPsec VPN Deployments. The most basic form of IPsec VPN is represented with two VPN endpoints communicating over a directly connected shared media, or dedicated circuit, which closely resembles bulk encryption alternatives at Layer 1 and 2 of the OSI stack (see Table 1-1 for VPN technologies and the OSI stack).
