Network requirements

The Wireless Gateway communicates towards the cloud via the IT network of the customer using IPv4.

The gateway must receive an IP address from a DHCP server; configuration of the gateway in combination with a static IP address (which is less commonly used) is not possible.

The communication between the Wireless Gateway and the cloud requires HTTPS, which uses the standard TCP-port 443.

This port is commonly used for access to the internet via a web browser. However, it needs to be validated with an IT representative of the end-customer whether their network has standard measures in place to block access to wired LAN connections.

In that case, the block needs to be cancelled, preferably with unrestricted access to IP addresses on the internet.

As the gateway always sets up connections from the gateway to the cloud, this is secure and avoids problems with load balancers that are typically used by cloud providers.

The system also needs the UDP port 123 to be open. This port is used for time synchronizing using the Network Time Protocol (NTP).

If firewalls are used to protect the network of the endcustomer, it is necessary to make sure that the following hosts can be connected to:

Classical firewalls typical provide protection at address level rather than host name level.
For that it is recommended to remove the restriction for the specific LAN port that is used to connect the gateway, or free up and address range used to map these host names.
Summary of requirements to connect the system:

  • Ethernet port with live LAN, connected with the IT network of the customer

  • IPv4 via DHCP server available

  • Port TCP 443 opened on the router

  • Port UDP 123 opened on the router
