Murus Services

Murus Services lets you configure and manage a few network services for OS X. Most of these services are part of OS X and are preinstalled on your Mac, but are hidden under the hood and disabled, while some others are made available by the open-source community.

You can run VPN server, web proxy, DHCP, FTP, TFTP, telnet, rlogin, and RSH services and add new static routes in a few mouse clicks.
