What is the benefit of the PoE+ ports?
The integrated PoE+ ports (up to 2 x 30W) allow you to power compatible devices like VoIP phones, wireless access points, or 5G routers directly from the firewall, reducing the need for separate power supplies and simplifying installations.
What is the VPN throughput of the USG FLEX 100H?
The USG FLEX 100H provides a VPN throughput of 750 Mbit/s, supporting up to 50 concurrent VPN tunnels using IKEv2, IPSec, and SSL protocols.
How do I update the firmware on the USG FLEX 100H?
Firmware updates can typically be managed through the Zyxel Nebula cloud platform or directly via the device's web management interface. It is recommended to keep the firmware updated for security and performance.
Troubleshooting
Device not powering on
Ensure the power adapter is securely connected to the device and a working power outlet. Check the DC input voltage specification.
Cannot access the web interface
Verify the network connection between your computer and the firewall. Check the device's IP address and ensure your computer is on the same subnet or has a route to the firewall's management interface. Try accessing via the console port if available.
Slow network performance
Check the enabled security services (IPS, Anti-Malware, etc.) as they consume resources. Ensure firmware is up-to-date. Monitor CPU and memory usage via the device interface. Verify physical network connections.
VPN connection fails
Double-check VPN gateway, pre-shared keys, and authentication settings on both ends of the tunnel. Ensure the necessary ports are open on any intervening firewalls. Review VPN logs for specific error messages.
PoE ports not powering connected devices
Confirm the connected device is PoE-compatible and does not exceed the 30W PoE+ limit. Check the PoE status in the device's interface and ensure the feature is enabled for the relevant ports.
