Note:
*: This matrix with firmware ZLD5.1 or later.

  1. Actual performance may vary depending on system configuration, 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); IMIX: UDP throughput based on a combination of 64 byte, 512 byte and 1424 byte packet sizes.
  4. Anti-malware (with Express Mode) and IPS throughput measured using the industry standard HTTP performance test (1,460-byte HTTP packets). Testing done with multiple flows.
  5. Maximum sessions measured using the industry standard IXIA IxLoad testing tool.
  6. Including Gateway-to-Gateway and Client-to-Gateway.
  7. With Zyxel service license to enable or extend the feature capacity.
  8. This is the recommend maximum number of concurrent logged-in devices.
