14.7. VPN over IPsec - handbook - ipsec tools

14.7.1. Configuring a VPN on FreeBSD​

To begin, security/ipsec-tools must be installed from the Ports Collection. This software provides a number of applications which support the configuration.

- then when I go to ipsec-tools

under tree it links me to http://ipsec-tools.sourceforge.net/

which says the following:

Important Note

The development of ipsec-tools has been ABANDONED.

ipsec-tools has security issues, and you should not use it. Please switch to a secure alternative!

So my question is what should I do? and which alternative should I use instead? and why can't the handbook be updated?
