Purpose of the document<\/h2>\n

[\/vc_column_text][vc_column_text css=””]<\/p>\n

This sheet summarizes the network recommendations (firewall & router) required for the proper operation of the Gateway Light<\/strong>.
\nIt is intended for IT teams to correctly configure the network infrastructure.<\/p>\n

[\/vc_column_text][vc_column_text css=””]<\/p>\n

Basic Principles<\/h2>\n

[\/vc_column_text][vc_column_text css=””]<\/p>\n

    \n
  • The gateway initiates all its communications to the cloud (*outbound only*).<\/li>\n
  • No incoming ports need to be opened.<\/li>\n
  • Protocols used: MQTT over TLS, HTTPS, NTP, DNS.<\/li>\n<\/ul>\n

    [\/vc_column_text][vc_empty_space][vc_column_text css=””]<\/p>\n

    Network recommendations<\/h2>\n

    [\/vc_column_text][vc_column_text css=””]<\/p>\n

    Firewall<\/strong><\/h5>\n
      \n
    • Allow the gateway<\/strong> to connect outbound on TCP 443<\/strong> (HTTPS) to *.thethings.network<\/strong>, *.thethings.industries<\/strong> and *.cloud.thethings.industries<\/strong><\/li>\n
    • Allow the gateway<\/strong> to connect outbound on TCP 8883<\/strong> (or fallback 443) for secure MQTT (mTLS)<\/strong> traffic<\/li>\n
    • Allow the gateway<\/strong> to connect outbound on UDP 123<\/strong> to NTP servers<\/strong><\/li>\n
    • Allow the gateway<\/strong> to connect outbound on UDP 53<\/strong> to the configured DNS servers (internal or public)<\/strong><\/li>\n
    • We recommend whitelisting the listed domains<\/strong> in the firewall to avoid blocking<\/li>\n<\/ul>\n
      Addressing<\/strong><\/h5>\n
        \n
      • In DHCP<\/strong>, ensure the gateway correctly receives network parameters: default gateway<\/strong>, DNS<\/strong><\/li>\n
      • In Static IP<\/strong>, configure parameters properly and set DNS if needed to 8.8.8.8<\/strong> (Google DNS)<\/li>\n<\/ul>\n
        DNS<\/strong><\/h5>\n
          \n
        • The gateway must be able to resolve domain names<\/strong> via internal or public DNS servers<\/li>\n
        • Example: access possible to 8.8.8.8 port 53<\/strong> (Google DNS)<\/li>\n
        • The domains *.thethings.network<\/strong> and *.thethings.industries<\/strong> must be reachable<\/li>\n<\/ul>\n
          Proxy<\/strong><\/h5>\n
            \n
          • If an HTTPS proxy is used, it must allow the gateway<\/strong> to communicate with the listed domains without TLS inspection<\/li>\n
          • Authenticated proxies<\/strong> are not supported<\/li>\n<\/ul>\n
