Designed for ease of use, SmoothWall Express is configured via a web-based GUI andÂ requires absolutely no knowledge of Linux to install or use.
Almost any Pentium-class PC can be used, for example, an old low specification PC longÂ redundant as a user workstation or server. SmoothWall Express creates a dedicated hardwareÂ firewall, offering the facilities and real security associated with hardware devices.
