Install ClearOS

Prerequisites:

As per my personal experience with this firewall, 40-80 GB HDD, for a 20-25 user environment a Dual Core System with 4 GB RAM will be sufficient, but for a 50+ user environment a minimum of 8 GB RAM with minimum corei5 configuration is required. However in official documentation there may be some different hardware related instruction, but as per experience, above mentioned configuration will work smoothly. Minimum 2 LAN Cars (1 LAN, 1 WAN).
