Set Up IKEv2 VPN Server and Clients

Compared to IKE version 1, IKEv2 contains improvements such as Standard Mobility support through MOBIKE and improved reliability. This is my personal snippet to set up IKEv2 VPN server & clients for multiple servers.

Snippets

Configure IPsec/XAuth VPN Clients

IPsec/XAuth mode is also called "Cisco IPsec". This mode is generally faster than IPsec/L2TP with less overhead. IPsec/XAuth ("Cisco IPsec") is natively supported by Android, iOS, and MacOS. There is no additional software to install for them.

Snippets

Configure IPsec/L2TP VPN Clients

This is the next part after you successfully set up your own IPsec VPN server. Following these steps allow you to configure your Android, iOS, MacOS, and Linux machine using IPsec/L2TP VPN.
