What is the difference between IPsec VPN and SSL VPN?

IPsec or Internet Protocol Security VPN encrypts packets with AES-256 encryption.

They offer better performance, but require the user to configure a certificate.

A SSL/TLS VPN works with an IPSec protocol in the back. As a result, it offers better user experience (the clients are automatically configured), but does not offer security as good as IPsec-based products do. And the other way round, for VPN tunnels it can make up for poor security performance with higher speeds and stability.

The VPNs market covers a wide range of technologies. However, some of them overlap with the market of VPN services. That is why, if you read this tutorial we will go over all the main types of the VPNs, starting from the free ones to the paid ones.

VPN types: As I mentioned above, the VPN types can be classified into three groups: Those that use AES-256 protocol for encryption - IPsec-based VPNs (Internet Protocol Security VPN);. Those that use S/MIME-SMTP authentication - SSL VPNs (Secure Sockets Layer VPN);. Types that use HTTP POST/GET for authenticating requests - HTTP-based VPNs. IPsec-based VPNs: Internet Protocol Security, abbreviated as IPsec-based VPN, is VPN technology that uses the AES-256 algorithm for packet encryption. Its first release was back in 1998 by the U. Department of Defense.

It works based on IPsec, which consists of the Internet Security Association and Key Management protocols. It allows users to encrypt traffic sent across the network or internet link. In the best case, IPsec-based VPN is used for confidential Internet transmissions only.

IPsec-based VPN is usually installed as a free module on client computers. In order for the connection to be established, users have to set up a certificate (and then log in). IPsec requires a computer administrator's consent.

IPsec is not only suitable for secure data transfer; it is also used for IP routing. One important benefit of IPsec as a security solution is its high security and reliability. The technology has been around for more than 20 years, and it is one of the key solutions for data confidentiality.

What is the difference between SSL and IPsec VPN?

Does it matter that I set both SSL and IPsec to VPN in DD-WRT (v24-sp1-v2.12r1.01)?
How do I choose between SSL and IPsec VPN? SSL VPN: It's a VPN, that means you can connect from outside of your local network. It's a VPN, that means you don't need to have a private address (eg IPv4). It's a VPN, that means you don't need to have a port open on your router. You don't need to have specific certificates. You don't need a specific VPN program. It's a VPN, but not that VPN: IPsec is what is used for VPN. You can only connect to hosts/services that support IPsec, so it's not a general VPN protocol. You need a specific VPN program (eg the Cisco client) and it's not a free/open protocol. You need a specific VPN certificate. Both are used for VPNs, so yes it does matter that you select both.

What is a disadvantage of a VPN that uses SSL instead of IPsec?

I know that VPN is like 'a shield' which hides your identity to the outside world and it's very useful when you need to hide your IP from the outside world, especially when your ISP is blocking it's traffic.

I'm trying to get a simple VPN that I can use at home (as I am not very good at configuring VPN on my own) and I'm asking myself if I should choose a VPN that uses SSL or IPsec? SSL vs IPSec is mostly about how much the VPN-end of things will use your internet bandwidth. SSL tends to be more computationally expensive, requiring more processor power for encryption and decryption. IPSec typically has more overhead, so less bandwidth usage. Since your VPN needs will be different for each connection, I would recommend running both in parallel, and using whichever is more bandwidth efficient.
