This is a port of OpenBSD's OpenIKED to different Unix-like operating systems, including Linux, macOS, FreeBSD and NetBSD.
The official documentation for OpenIKED are the man pages for each tool:
and the OpenBSD VPN FAQ.
Portable OpenIKED is built using cmake.
It requires a working C compiler, standard library and headers, a
yacc compatible parser generator, libevent, and libcrypto from either
LibreSSL or OpenSSL.
