Looking at automatically blocking particular devices on your network? PacketFence is for you. PacketFence can combine the following detection mecanisms to effectively block network access from those unwanted devices :

• DHCP Fingerprint
  PacketFence can block devices based on their DHCP fingerprint. Nearly every operating systems out there have an unique DHCP fingerprint. PacketFence can make use of this information and block network access from those devices. Based on DHCP fingerprints, you could automatically block, for example :
  
  • Sony PlayStation devices or any other game consoles
  • Wireless access points (WAPs)
  • VoIP phones
    
    
• User-Agent
  PacketFence can block devices based on the provided User-Agent when those particular devices perform network activity using their embedded Web browser. Using this, you could automatically block, for example :
  
  • Apple iPod or iPhone devices
  • Everyone using an old Microsoft Internet Explorer (IE) release
    
    
• MAC addresses
  PacketFence can block network access to devices having a specific MAC address pattern. Using this, you could automatically block, for examples, all devices from a specific network vendor.
