I'm new to Linux things so everything seems confusing. I want to enable some VPN prequisities to create VPN in Linux server 12.04 Networking support (NET) [Y/n/?] y PF_KEY sockets (NET_KEY) ...
Is it possible to create a separate device (like tun made by openvpn) for ipsec? If yes how can I do it?
Complexity of installation of IPSec is not an issue. I would like to know which one will provide a faster connection for tunneling.
