If someone used l2tp the same way I want to use on CentOS 7 please give me some advice.

l2tp, by itself, offers no encryption. Notably, that means that your password is going to cross the network in clear text. Bare l2tp is the VPN equivalent of telnet. I really strongly recommend that you reconsider.

ipsec, by itself, is a much better and easier way to achieve your goal. It will require less setup, and offer better security. There's no down side; ipsec is clearly a better choice for connecting two systems over an unsecured network.

l2tp is typically used in conjunction with ipsec, for mobile clients. The reason is that l2tp integrates with external authentication (RADIUS, LDAP, Active Directory, etc) better than ipsec alone does. That's great when you have a group of users that you want to have individual authentication keys, but it's not a good fit for connecting one server to another.
