Milesight UR32L-L0GEU 4G Router with 2 x Ethernet

Industrial 4G Router – Cellular WAN and VPN in a Compact Lite Package

The Milesight UR32L (UR32L-L0GEU) is a Lite Series industrial 4G LTE Cat 4 router built for M2M and IoT deployments where the requirement is a reliable cellular connection, a full VPN stack, and remote management – without serial ports, digital I/O, or Wi-Fi. It connects to a single SIM, provides two 10/100 Mbps Ethernet ports, and falls over automatically from an Ethernet WAN to cellular if the primary link drops. It draws 1.8 W in normal operation, runs from 9 to 48 V DC, and operates from -40 to +70°C in an IP30 metal enclosure on a DIN rail or wall mount.

The VPN capability is not cut down despite being the Lite model. The UR32L supports OpenVPN client and server, IPsec client and server, WireGuard, ZeroTier, GRE, DMVPN, L2TP, and PPTP. Remote management runs through Milesight DeviceHub and the Milesight Development Platform, covering mass configuration, firmware updates, and status monitoring across deployed fleets. For deployments that need serial ports, digital I/O, dual SIM, or RS485 connectivity, the UR32 Pro Series is the step up.

What the UR32L-L0GEU is Used For

Cellular Backup WAN for Fixed-Line Connections

The UR32L’s automatic WAN failover makes it a direct fit for sites with a primary fixed-line connection that need cellular backup when the broadband goes down. The router monitors the Ethernet WAN link continuously and switches to 4G automatically on failure. When the fixed line recovers, it falls back without manual intervention. This covers retail branches, small offices, kiosks, and any site where an outage means lost transactions or unmonitored equipment.

Remote IP Device Connectivity

For remote sites with IP-connected devices – network cameras, IP sensors, Ethernet PLCs, or managed switches – the UR32L provides the cellular WAN link and VPN tunnel back to the head-end or cloud platform. A fixed IP SIM makes the site addressable for inbound polling or remote access. The two Ethernet ports allow a LAN device and a WAN connection to coexist, or both ports can be configured as LAN for a local switch connection.

Simple M2M and Remote Monitoring

Where a remote site sends data to a cloud platform or SCADA system over cellular and the local devices all have Ethernet ports, the UR32L covers the use case without paying for hardware not required. Environmental monitors, smart meters with Ethernet outputs, energy management gateways, and IP-based alarm panels all connect directly to the LAN port. The data path goes cellular over a WireGuard or IPsec tunnel to the operations centre.

Payment Terminals and Retail Kiosks

POS terminals, self-service kiosks, and vending machines that connect over Ethernet need a reliable always-on cellular link with a fixed IP for inbound VPN access and remote management. The UR32L provides this with minimal hardware overhead. There is no Wi-Fi radio, which removes a wireless attack surface on sites where that matters. Pair with a fixed IP SIM and a WireGuard or IPsec tunnel for secure inbound access from the payment processor or support team.

Temporary and Portable Site Connectivity

The UR32L runs from 9 to 48 V DC and draws 1.8 W, which makes it practical for battery or solar installations. Its compact size and DIN rail mounting suit temporary distribution boards on construction sites, welfare units, and pop-up retail. When the site moves on, the router travels with it and reconnects to the management platform automatically.

Frequently Asked Questions

Does the UR32L-L0GEU support dual SIM?

No. The UR32L has a single SIM slot (Mini SIM, 2FF format). WAN resilience comes from the automatic failover between the Ethernet WAN port and cellular – if the primary Ethernet connection drops, the router switches to 4G. For hardware dual SIM failover between two carrier networks, the UR32 Pro Series carries two SIM slots. See the Milesight 4G router range for a full comparison.

Does the UR32L have a serial port or digital I/O?

No. The UR32L is the Lite Series and does not include RS232, RS485, digital input, or digital output. It provides cellular WAN and two Ethernet ports only. For serial instrument connectivity or digital alarm monitoring, the UR32 Pro Series includes an RS232 or RS485 port and galvanically isolated digital I/O as standard.

What SIM card does the UR32L take?

The UR32L takes a Mini SIM (2FF format). For remote access, VPN tunnelling, and any deployment requiring inbound connections from a head-end or SCADA system, a fixed IP SIM is the right choice. Standard SIM cards sit behind carrier-grade NAT, which blocks inbound connections. A fixed IP SIM assigns a routable public address to the router. See IoT SIM cards for all available options.

What VPN protocols does the UR32L support?

The full list is: OpenVPN (client and server), IPsec (client and server), WireGuard, ZeroTier, GRE, L2TP (client), PPTP (client), and DMVPN (spoke). The VPN capability is not reduced on the Lite model. For site-to-site tunnels and secure remote access over cellular, WireGuard and IPsec are the most practical choices. See VPN on cellular routers for protocol guidance.

Can I manage multiple UR32L routers from one platform?

Yes. Milesight DeviceHub and the Milesight Development Platform provide centralised configuration, firmware updates, cellular diagnostics, and event alerting across fleets of deployed units. SNMP v1/v2c/v3, TR-069, and HTTP(S) API are available for integration with existing NMS platforms. MilesightVPN provides a private overlay network between units if needed.

How does the WAN failover work on the UR32L?

The UR32L monitors the Ethernet WAN link using configurable detection methods and switches to the cellular connection automatically when the link fails. When the Ethernet WAN recovers, it falls back without manual action. This failover runs between Ethernet and cellular only – it is not a SIM-to-SIM failover, since the UR32L carries a single SIM. For sites needing cellular-to-cellular carrier failover, the UR32 Pro Series with dual SIM is the correct product.

UR32L Variant Comparison

The UR32L range has two configurations. This page covers the UR32L-L0GEU, the base variant with 4G cellular and 2x Ethernet. The UR32L-L0GEU-P adds 802.3af/at PoE PSE output on both LAN ports for powering IP cameras or other PoE devices directly (48 V DC input required).
