Cadena’s Solutions
Cadena’s solution is in the form of an affordable Linux software firewall installation. The Linux firewall will be installed on a CPU (without monitor and accessories) that is positioned between the ADSL modem (and router in case of leased line) and the network hub. The CPU must be stable, use a stable brand name machine, the configuration requirements can be minimal. A Pentium III second hand is sufficient.
