Your sensor communicates with multiple systems to download configuration and upload test results. Below is a list of the minimum URLs which you will need to make accessible in order for the sensor to function correctly. Any additional services which you set up for testing might also need to be allow-listed in order for them to be tested correctly.
This is the primary URL for all sensor communication with our backend systems
Please note: Do not use SSL decryption for this URL (https://device-gateway.capenetworks.io).
These are additional URLs that the sensor uses to upload results and download over the air firmware updates, tools, and patches:
The sensor uses one of the following methods to get the correct time:
- NTP using 0.pool.ntp.org
- If NTP is not available, the sensor will get the correct time via HTTP from http://device-gateway.capenetworks.io/ port 80. The sensor will expect HTTP response code 204 with no content.
The following URLs are used by the sensor to test whether it has external connectivity. If it can't access them then the sensor will report a "No connectivity" issue on the dashboard. No sensitive data is transferred to or from these locations.
Warning: if your network has a Captive Portal, depending on your setup, you probably do NOT want to allowlist the following URLs. This is because the sensor might not be properly redirected to the Captive Portal. Instead, the following URLs should be accessible, but result in a Captive Portal redirect response for unauthenticated clients.
