The new management team was led by Georg Ell, previously Director of Western Europe at Tesla, who was appointed as Group CEO in May 2018.

Created using Red Hat Linux, Smoothwall GPL originally had two simple functions: control the modem to dial and hang up, and to route TCP/IP packets from the LAN to the Internet connection, and back again.

It used the open source platform again as a base but included SmoothGuard, and would have permitted customers to make email support requests directly from Smoothwall Ltd.

These modules included SmoothGuard (content filtering proxy), SmoothZone (multiple DMZ) and SmoothTunnel (advanced VPN features).

Released on 9 May 2005, Smoothwall Advanced Firewall targeted the enterprise market directly by bundling Corporate Server with all available add-on modules, and adding further functionality, including Active Directory, eDirectory & LDAP authentication and the capability to use up to 20 network interfaces with external connection load balancing.
