Dear beloved Zenarmor Users,
IPSec is a collection of communication protocols that provide secure connections over a network. The phrase "IPsec" is an abbreviation where "IP" represents "Internet Protocol" and "sec" represents "secure."
OPNsense provides VPN connectivity for both branch offices and remote users (Road-Warrior). Setting up a single, secure private network that connects several branch offices to a central location is simply accomplished using the OPNsense web user interface.
This guide will explain the process of configuring an IPsec site-to-site VPN tunnel using an OPNsense firewall.

If you wrote a documentation for IPSec on OPNSense, it would be useful if you didn't use the legacy settings.
