Note:
* This matrix with firmware ZLD 4.20 or later.

  1. Actual performance may vary depending on network conditions and activated applications.
  2. Maximum throughput based on RFC 2544 (1,518-byte UDP packets).
  3. VPN throughput measured based on RFC 2544 (1,424-byte UDP packets).
  4. With Zyxel Device Upgrade License, this is the recommend maximum number of concurrent logged-in devices.
  5. Maximum sessions measured while UTM disabled using the industry standard IXIA 1xLoad testing tool.
  6. Including Gateway-to-Gateway and Client-to-Gateway.
  7. With Zyxel SSL VPN License, this is the recommend maximum number of concurrent VPN users.
  8. With Zyxel AP Controller License, this is the recommend maximum AP capacity of concurrent users.
  9. SafeSearch function in CF2.0 need to enable SSL Inspection firstly and not for small business models.
  10. Hotspot Management supports for ZyWALL 310 and ZyWALL 1100 in firmware ZLD4.20 or later; and for ZyWALL 110 in firmware ZLD4.25 or later.
