In versions older than FreeBSD 11.0 the generic kernel does not come with IPsec support enabled. So you will have to compile your own kernel. The NAT Traversal patch is included in the kernel sources since FreeBSD 8, so you don't have to apply any patches yourself, if you need that feature. The IPsec mechanism provides secure communication for IP layer and socket layer communication. This section should explain how to use them. For implementation details, please refer to The Developers' Handbook. The current IPsec implementation supports both transport mode and tunnel mode.

L2TP VPN in FreeBSD - Wiki Start with a FreeBSD RELEASE 9 or 9.1 install including full sources and the ports collection. The excellent FreeBSD handbook will guide you through this process. There are a number of things we need which are not in the GENERIC kernel, so you will need to recompile the kernel , but this is incredibly simple in FreeBSD compared with Linux: IPsec — Choosing configuration options | pfSense Documentation Aug 06, 2019
Since Mac OS X's IPSec is derived from the one in FreeBSD and NetBSD it's not directly linked to the IPSec in OpenBSD. This doesn't mean that it hasn't been compromised, all code is suspect - even implementations in Linux and Windows - simply because it seems like people ha.
VPN — IPsec — Routed IPsec (VTI) | pfSense Documentation Routed IPsec (VTI)¶ Route-based IPsec is an alternative method of managing IPsec traffic. It uses if_ipsec(4) from FreeBSD 11.1+ for Virtual Tunnel Interfaces (VTI) and traffic is directed using the operating system routing table. It does not rely on strict kernel security association matching like policy-based (Tunneled) IPsec. GitHub - zoulasc/racoon2: The Racoon2 project is a joint The Racoon2 project is a joint effort which provides an implementation of key management system for IPsec. The implementation is called Racoon2, a successor of Racoon, which was developed by the KAME project. It supports IKEv1, IKEv2, and KINK protocols. It works on FreeBSD, NetBSD, Linux, and Mac OS X. Racoon2 is provided under a BSD-style license.
