Here’s what really sums up the VPN protocol speed and security: There’s a lot of misinformation regarding VPN protocols on the internet – mainly that the protocols themselves can be compared. Naturally, there are other protocols besides IKEv2, and people always want to know how they compare with one another. How does IKEv2 compare to other protocols? So, if your VPN provider configures IKEv2 properly, it will not have security issues. That being said, IKEv2 has no known vulnerabilities on its own.

It also goes on to explain why it’s usually referred to as IKEv2 rather than the full name IKEv2/IPsec (in short, it’s because IKEv2 was implemented in 2005 – a much newer development than IKEv1 and IPsec of 1995). What does IPsec do exactly? I’m glad you asked – we have a great article explaining the basics of IPsec VPNs. It then takes all the data – the IP addresses, the security measures used, the ports utilized in the connection – and gives it to IPsec, which then uses the security associations to encrypt the traffic. Working together, IKEv2 uses a few data packets to establish a security association with the server. It allows it to process data at much greater speeds. On the other hand, IPsec runs in the kernel, the deep layer of the computer systems that controls everything. It allows it to easily retrieve any configuration data required for a security association.

IKEv2 runs in the user space, which grants it access to data storage. The merging of IKEv2 and IPsec is one of the secrets of its speed. IKEv2 was joined to IPSec by a joint effort between Microsoft and Cisco. Īll of this means that IKEv2 works on publicly tested and widely accepted standards of cryptographic security. Then they create a “shared secret” via a Diffie–Hellman key exchange algorithm, which is best explained here. IKEv2 then uses X.509 certificates ( a standard of identifying that a public key belongs to you ) for the devices to introduce themselves. IKE builds upon the Oakley Key Determination Protocol and ISAKMP, both of which define widely accepted methods for two devices to exchange data needed to create security keys (for encrypting data ) via an unsecured connection.

Make sure you use your VPN username and password and NOT the website account credentials ( What is the difference?).Ĭhoose Dynamic from the Address Mode drop-down menu (7).Ĭheck the Enable Manual DNS Assignment checkbox (10).Įnter the Public Google DNS or other open DNS addresses in the Primary DNS Server and Secondary DNS Server fields (11).IKEv2 (or IKEv2/IPsec) handles the security association ( the negotiations of what kind of security will be used ) between your device and the VPN server, and IPsec carries all the data transmission. You can find them in your account on our website, by going to Settings. You can find all the available servers in your account on our website, by going to Settings.Įnter your VPN username and password (6). That happens because the connection does not use IPSec.Įnter the IP address of the VPN server you want to connect to in the PPTP / L2TP Server Address field (5). Important! By setting up a L2TP VPN on Tenda routers your IP will be changed but your traffic will NOT be encrypted. Make sure Internet Connection Setup (3) from Advanced (2) is selected.Ĭhoose PPTP / L2TP from Internet Connection type drop-down box (4). Click on Advanced (1) from Internet Connection Setup.
