Connection Over IPSec VPN. This topic describes one way to set up a connection between an Oracle Cloud Infrastructure Classic IP network and an Oracle Cloud Infrastructure virtual cloud network (VCN). The connection runs over an IPSec VPN. Another option is to have Oracle set up a connection over the Oracle network.

IPSec connections should only be used if they have been set up by an expert. If set up correctly, IPSec offers the highest possible level of security. When connecting to a commercial VPN provider, avoid PSK authentication. OpenVPN is the weapon of choice for most users. The setup process is easy and flexible, the security is comparable to IPSec.

Aug 13, 2019 · This VPN protocols guide is meant to serve as a basic overview of the main VPN protocols in use today: OpenVPN, L2TP/IPSec, IKEv2/IPSec, WireGuard, PPTP, and SSTP. For more in-depth information on each protocol, you can examine references from the respective developers. Apr 04, 2018 · OpenVPN seems to be the best option. If you have to use another protocol on Windows, SSTP is the ideal one to choose. If only L2TP/IPsec or PPTP are available, use L2TP/IPsec. Avoid PPTP if possible — unless you absolutely have to connect to a VPN server that only allows that ancient protocol. Image Credit: Giorgio Montersino on Flickr On the downside, as with L2TP/IPsec you may need to manually open firewall ports to enable the IKEv2/IPsec connection. Many of the top VPN services have an option to use this protocol. For example NordVPN, IPVANISH , ProtonVPN and more. More often than not, IPSec VPN ports are usually open in the firewall. If it is not, you can make it work by opening UDP port 500. This allows ISAKEP traffic to get forwarded through your firewalls. It also permits IP protocol IDs 50 to allow ESP traffic and 51 to allow AH traffic. There are three major families of VPN implementations in wide usage today: SSL, IPSec, and PPTP. OpenVPN is an SSL VPN and as such is not compatible with IPSec, L2TP, or PPTP. The IPSec protocol is designed to be implemented as a modification to the IP stack in kernel space, and therefore each operating system requires its own independent

StrongSwan is a implementation of IPSec which is multi-threading. If you're going to encrypt EAS256 on a 10Mbps connection, 1 core of a WRT1900ACS will be fast enough for oVPN to encrypt and get roughly 9Mbps effective over that connection.
