In order to successfully connect your Cel-Fi QUATRA system to the WAVE Portal using a LAN connection, please follow the steps below to check your firewall settings.
Step 1. Download the CEL-FI WAVE Field Tool
Step 2. Launch the WAVE field Tool
Step 3. Click on the "Cloud Connection" menu item
Step 4.Temporarily disable Wi-Fi on your PC to run this test
Step 5. Connect a live Ethernet cable to your PC
Step 6. Click the "Test Connection" button
Step 7. A GREEN LED means the check passed, while a RED LED indicates a failure for that specific item. If any item displays a red LED, please contact your IT administrator for assistance with network access.
The WAVE system requires the following networking access:
- HTTPS on port 443
- DNS (standard port for DNS is 53)
- DHCP (standard port for DHCP is 67)
- NTP (standard port for NTP is 123)
Connections are always initiated from the device side. There is no need to configure any inbound ports on the firewall, thereby reducing exposure to external threats. To achieve both these attributes and still remain responsive to external commands, QUATRA uses Web sockets. Web sockets is a lightweight IETF protocol that is built on top of HTTP and establishes persistent TCP connections between a client and server. Since the connection is initiated on client side and uses regular HTTPS, typically no special inbound firewall configuration is needed, yet commands can be delivered to the device in real-time.
