Built upon the foundation of the FreeBSD 11.0 operating system, OPNsense 17.1 promises to be a major release featuring a large number of new technologies and functionalities, among which we can mention a very useful SSH (Secure Shell) remote installer, PHP 7.0 support, native PAM (Pluggable Authentication Module) authentication against 2FA, new Tinc VPN and FTP proxy plugins, as well as support for Czech and Italian languages. Furthermore, this first Beta release of OPNsense 17.1 updates the Intel em driver to version 7.6.2 as a plugin, introduces IPsec tunnel isolation mode for interoperability, improves the security of passwords, rewrites the Nano images to support growfs, adds system secondary console support with new Mute and EFI options, and makes the firewall rules and authentication methods fully pluggable.
