Firewall Management

Firewall management allows you to configure network access.

You can configure items such as:

  • Enable or disable ports.
  • Configure port numbers per interface (Eth1, Eth2, WiFi, GPRS/3G), except where noted in Port Settings.
  • Enable upstream network access.

Disabling unused ports (determined by your network selection in Settings > General Settings > Network Settings) can help prevent unauthorized access.

** For default port settings, see Port Settings

Upstream Network Access

This feature allows downstream devices to access servers (such as DNS, SNTP, and SMTP) on the upstream network.

Upstream Network Access is disabled by default. It is recommended to leave this setting disabled unless it is required to publish data or send event messages from downstream clients.
