📡 MIVO Connect – Network Guide#

This guide summarizes common network scenarios for MIVO Connect and provides answers to questions related to IP configuration, ports, firewalls, and WAN or LTE connectivity.

1. 🧩 Standard Installation with DHCP#

❓ Questions & Answers: - Does the device automatically get an IP address via DHCP?
Yes, MIVO automatically requests an IP address via DHCP during startup.

  • What happens if no DHCP server is available?
    The device waits for an IP address and indicates this with a blinking red WAN LED.

  • How is this shown through MIVO’s LED indicators?
    Blinking red WAN light = No IP address assigned.

📌 Scenario: Common in most networks with a standard router.

2. 🛠 Static IP Address#

❓ Questions & Answers: - When must a static IP address be configured?
When DHCP is unavailable or a fixed IP is required for firewall rules.

  • How is this configured via the web interface?
    Go to System > Network in the MIVO Connect interface.

  • Which settings are required?
    IP address, subnet mask, gateway, and DNS servers must be entered manually.

📌 Scenario: Common in larger networks or industrial systems.

3. 🌐 Wired WAN Connection (Ethernet)#

❓ Questions & Answers: - What happens if the WAN cable is not connected?
The WAN LED will be solid red. No link detected.

  • How do you verify that MIVO has internet access?
    Use the status view in the interface or perform an ICMP ping (e.g. to www.google.com).

  • Which port/protocol is used for internet connectivity tests?
    ICMP (ping).

📌 Scenario: Primary solution for buildings with wired internet.

4. 📶 LTE – Mobile Network#

❓ Questions & Answers: - When should LTE be used instead of a wired connection?
When no wired connection is available or as a backup connection.

  • How is LTE activated in the interface?
    Go to System > Network and enable LTE.

  • What is required for LTE to work?
    SIM card, correctly installed antenna, and configuration via the interface.

📌 Scenario: Ideal for temporary installations or remote locations.

5. 🔄 Router in Front or Behind MIVO#

❓ Questions & Answers: - Should MIVO be directly connected to the internet or behind a router?
Most commonly, MIVO is placed behind a NAT-enabled router.

  • Which outbound ports must be opened in the firewall?
    80 (HTTP), 443 (HTTPS), 2022 (Easy Access), 21 (FTP for export).

  • Is NAT or port forwarding required?
    Only for inbound traffic like VPN access.

📌 Scenario: Common in corporate or centrally managed networks.

6. ☁️ Export to External Systems (FTP/HTTP)#

❓ Questions & Answers: - Which ports must be allowed outbound for export?
Typically port 21 for FTP and port 443 for HTTPS.

  • Do you need to open port 21 (FTP) or 443 (HTTPS)?
    Yes, depending on the chosen export method.

  • How is authentication handled?
    Via username/password or e.g., Bearer Token in the HTTP header.

📌 Scenario: Used when sending data to external platforms or systems.

7. ⚙️ Modbus TCP Communication#

❓ Questions & Answers: - How is Modbus TCP configured in MIVO Connect?
Add a "Modbus TCP Interface" under Infrastructure > Add.

  • Which IP and port are used (usually 502)?
    Port 502 is standard; IP address is entered manually.

  • Does the firewall need to allow inbound traffic to MIVO?
    No, MIVO acts as a client/master and initiates outbound connections.

📌 Scenario: Used to measure electricity, heat, water via external Modbus devices.

8. 🔐 VPN and Secure Remote Access#

❓ Questions & Answers: - Does the OpenVPN server need to be enabled on MIVO (port 1194)?
Yes, if you want to access MIVO remotely via VPN.

  • When is VPN access required?
    When remote access to the web interface is needed outside the local network.

  • Does this require port forwarding?
    Yes, port 1194 (UDP) must be forwarded in the router.

📌 Scenario: For remote maintenance, support, or accessing off-site devices.

9. 🧪 No Internet – Troubleshooting#

❓ Questions & Answers: - How can you tell the device has no internet access?
Check status view in the interface or observe LED indicators.

  • How do you distinguish between local issues vs. DNS or firewall issues?
    Use MIVO’s tools to test ping and DNS resolution.

  • Which ports should be checked first?
    ICMP (ping), 53 (DNS), 80/443 (HTTP/HTTPS).

📌 Scenario: Useful when no data is reporting or remote access fails.

10. 🏢 Multiple MIVO Units in Larger Networks#

❓ Questions & Answers: - How do you avoid IP conflicts?
Use static IP addresses or reserved DHCP leases.

  • Does each unit need its own static IP?
    Yes, it simplifies management and integration.

  • How do you handle VLANs, segmented networks, or gateway settings?
    Set appropriate network parameters per unit based on your topology.

📌 Scenario: For buildings, industrial sites, or large deployments.

🛠 Port Overview#

Port Protocol Usage
80 TCP Web GUI, software updates
443 TCP HTTPS (Easy Access, cloud API)
502 TCP Modbus TCP
2022 UDP Easy Access data channel
67/68 UDP DHCP request/response
53 UDP/TCP DNS
1194 UDP OpenVPN
21 TCP FTP export (e.g. Elvaco)

🔍 Network Diagnostics Tips#

  • LED Indicators: Use WAN/LAN/RS485/MBUS LEDs for quick diagnostics.
  • Web Interface: Live logs and connection status are visible in the browser.
  • Test Ports: Always check ICMP, 53, 80, and 443 when troubleshooting.
  • Offline Situations: LTE is a solid alternative if the wired line fails.
