• Wireless: Connect to the router’s WiFi Hotspot SSID.

2. Open a web browser and navigate to the router’s default gateway IP address (http://192.168.4.1) of the aggregation router.
3. Enter your Username and Password to log into the Web Management Console.
4. Click Advanced Settings and select the LAN Settings tab.

5. To configure the Router LAN IP Address, locate the Router IP Address field.
6. Enter the desired local gateway IP address (default: 192.168.4.1).
7. Enter the corresponding Subnet Mask (default: 255.255.255.0).
8. View connected devices. Scroll down to the Connected Devices List section on the Home screen.
9. Review the real-time list of connected client devices displaying:

• Hostname
• MAC Address
• Assigned IP Address
• Connection Status

10. Configure Hostnames Mapping (Optional). To assign a custom hostname to a specific device:

• Scroll to the Hostnames Mapping Table.
• Click Add New Mapping.

11. Enter the following details:

• Hostname: Custom name for the device (e.g., Cam_Encoder_01)
• MAC Address: The device’s MAC address (e.g., 00:1A:2B:3C:4D:5E)
• Assigned IP: The static IP address to reserve for the device (e.g., 192.168.4.105)

Important: Ensure the MAC address is entered consistently in either all uppercase or all lowercase to avoid mapping failures.

12. Click Save to apply all LAN configuration changes.

Note: Allow 5–10 seconds for the router to update DHCP and LAN parameters.

13. Reconnect any affected client devices to receive updated IP assignments.
14. To verify the configuration on a connected client device, run ipconfig (Windows) or ifconfig / ip addr (Linux/Mac) to confirm the assigned IP is within the configured DHCP pool range.
15. Ping the router gateway (192.168.4.1) to verify LAN connectivity: Enter ping 192.168.4.1
16. Return to the Connected Devices List in the Web UI to confirm the device appears with the correct hostname and IP address.
17. For external devices that are connected to the router using a network cable, the IP allocation method uses DHCP by default. As the IP address and mask of the router change, the address assigned to the devices will also change.

P2P settings

The P2P function is used in typical applications to interconnect between a device connected to the router and the device under the aggregation gateway server. To learn more about enabling and using the P2P function, refer to “Typical P2P deployment scenarios.”

Modem configuration

The Modems configuration window Provides control and diagnostic options for the three embedded 5G modem slots (Quectel RM500Q / RM520N-GL).
General mobile phone SIM cards and IoT cards have default configurations, which need to be modified under special circumstances such as private APNs, roaming overrides, IoT-specific credentials, or enterprise fixed-IP SIM configurations.
To set the parameters of the mobile SIM card for internet access:

To configure 5G SA (Standalone) vs. NSA (Non-Standalone) mode and modem band preferences:

1. Open a web browser on a device connected to the router via LAN or WiFi.
2. Log into the TVU Nano Router Web Management UI.
3. Click Advanced Settings and select the Modems tab.

4. In the Select SIM Slot dropdown menu, choose the modem slot you want to configure:

• Slot 1 (e.g., Quectel RM500Q / RM520N-GL)
• Slot 2
• Slot 3

5. Check the current status indicator to verify the inserted SIM card and carrier details.
6. To Switch to the Manual / Network Mode Selection, under Mode Selection, toggle the mode to Manual if required to override automatic network locking.

7. Locate the Network Registration Mode / Network Lock selection dropdown.
8. Choose your desired 5G operating mode from the dropdown menu:

• 5G SA (Standalone): Forces the modem to connect exclusively to native 5G Core (5GC) networks without using a 4G LTE anchor band (ideal for low latency and dedicated 5G slicing where supported by the carrier).
• 5G NSA (Non-Standalone): Configures the modem to operate using 5G NR dual connectivity with a 4G LTE anchor band (ideal for wider coverage and standard 5G carrier networks).
• 5G SA / NSA Auto (Default): Automatically negotiates between 5G SA, 5G NSA, and 4G LTE based on real-time signal strength and carrier availability.
• 4G LTE Only: Restricts the modem to 4G LTE networks only.

9. Click Save to update the settings for the selected slot.
10. If you want the same 5G SA/NSA mode applied across all 3 embedded modems, click Apply All Slots.
11. Allow 10–30 seconds for the modem to re-initialize and complete network registration.

Transparent Mode

Transparent Mode (Bridge / Passthrough Mode) bypasses the router’s internal NAT (Network Address Translation). It passes the aggregated WAN uplink directly through to a downstream device (such as a hardware firewall, enterprise router, or broadcast encoder), allowing that downstream device to acquire an IP directly from the bonded uplink network.
The Transparent Mode feature lets you to transmit to a destination IP and Source IP transparently. When this feature is enabled, the IPs display as “0.0.0.0/0”. This function is disabled by default.

To enable and configure Transparent Mode:

1. Connect your computer to the TVU Nano Router via:

• Ethernet: Plug a LAN cable into one of the router’s GbE LAN ports.
• WiFi: Connect to the router’s Wi-Fi Hotspot SSID (TVU_Nano_5G_RD300).

2. Open a web browser and navigate to: http://192.168.4.1
3. Enter your Username and Password to log in.
4. In the top navigation bar, click the Advanced Settings dropdown menu.
5. Click the Transparent Mode tab.
6. Locate the Transparent Mode Status toggle switch at the top of the page.

7. Click the switch to set it to ON / Enabled.
8. Enter the Destination IP and Source IP. When using multiple addresses, they must be separated with a comma “,”.

Three types of address ranges are supported, including P2P settings. Supported address ranges are:

• Address segment: Defines a continuous range of IP addresses specified with a start and end address separated by a hyphen (-). For example:
• 192.168.4.1-192.168.4.32
• Mask form (CIDR): Defines a subnet block using standard CIDR prefix notation (IP/prefix). For example: 192.168.3.0/27
• Single address: Defines a discrete host IP address (equivalent to a /32 host route). For example:
• 192.168.100.100

9. Click Save. Saving restarts the router and interrupts all active connections.
10. To disable Transparent Mode, set the switch to OFF and click Save again. Moving the switch changes nothing until you save.

Configuration Notes:

• Validation: All three formats must use valid IPv4 addresses and must not overlap with active WAN interface subnets (e.g., cellular modems, WiFi WAN).
• P2P / Transparent Routing: These formats allow flexible routing rules—whether you want to pass through a single specific device, a small contiguous pool, or an entire subnet across the bonded connection.

Typical P2P deployment scenarios

This section describes how the P2P function configures interconnection between devices and routers using the same aggregation gateway.
The IP Range field under Advanced Settings › P2P Support takes only three forms, and several can be separated by commas:

• single host: 192.168.4.10
• CIDR: 192.168.4.0/24
• range: 192.168.4.1-192.168.4.32

The following shows two typical P2P deployment scenario examples:
Scenario 1: P2P between a device behind the Router and a device behind the aggregation gateway server.

Subnet Constraint (Important):

• Non-Overlapping Subnets: The local LAN subnet on the TVU Router side and the local LAN subnet on the TVU Router Server side must not overlap or be identical.
  • Example conflict: If the Router LAN is configured as 192.168.1.0/24, the Router Server LAN cannot also use 192.168.1.0/24.
• Virtual/Tunnel Subnet Isolation: Neither site’s local LAN subnet may overlap with the virtual P2P tunnel subnet / IP range assigned for the TVU point-to-point link.
• Routing Requirement: Each endpoint network must use a unique, distinct IP subnet (e.g., Router LAN: 192.168.10.0/24, Router Server LAN: 192.168.20.0/24, Virtual P2P Tunnel: 10.x.x.x/24) to prevent IP routing collisions across the tunnel.

Client A configures the Router:

• Router LAN: e.g.,192.168.10.0/24
• Turn P2P Support on, enter the IP Range, and click Save. Saving restarts the router and interrupts all active connections.

Scenario 2: P2P interconnection between devices connected to 2 routers under the same aggregation gateway server.
Strict Subnet Separation (No Overlap):

• Router A Local LAN Subnet, Router B Local LAN Subnet, and the Gateway Virtual Tunnel Subnet must all be distinct and non-overlapping.
  • Example Plan:
    • Router A LAN: 192.168.10.0/24 (Router IP: 192.168.10.1)
    • Router B LAN: 192.168.20.0/24 (Router IP: 192.168.20.1)
    • Aggregation Gateway Subnet / Tunnel: 10.100.0.0/24

DHCP / Gateway Settings on Client Devices:

• Client devices connected behind each router must use their respective router as their default gateway so packets targeting the other router’s subnet are forwarded into the tunnel.

Client A configures the Router:

• Router A LAN: e.g., 192.168.10.0/24 (Router IP: 192.168.10.1)
• Turn P2P Support on, enter the IP Range, and click Save. Saving restarts the router and interrupts all active connections.

Client B configures the Router:

• Router B LAN: e.g., 192.168.20.0/24 (Router IP: 192.168.20.1)
• Turn P2P Support on, enter the IP Range, and click Save. Saving restarts the router and interrupts all active connections.

P2P Configuration interface

P2P Support establishes a direct, encrypted Point-to-Point tunnel between two TVU Router units (or between a TVU Router and a designated remote server/peer node) across bonded 5G/4G/WAN uplinks, allowing low-latency LAN-to-LAN communication.

To configure P2P Support:

1. Open a web browser and navigate to http://192.168.4.1.
2. Log in with your credentials.
3. In the top navigation bar, click Advanced Settings and select P2P Support.

4. Enable the P2P Feature. Set the P2P Support toggle switch to ON.

Note: The IPs of the devices at both ends cannot be exactly the same. Enabling/disabling/modifying P2P settings will interrupt the network for about 2 seconds.

5. In IP Range, enter the subnets on this router that should be reachable over the tunnel, using the formats listed above. Separate multiple entries with commas.
6. Click Save. Saving restarts the router and interrupts all active connections.

NAT/No NAT server switching

NAT (Network Address Translation)
What it does: The device (router, transceiver, or gateway) sits between the local network (LAN) and the external/bonded network (WAN), translating private local IP addresses (e.g., 192.168.x.x or 10.x.x.x) into an external IP address.

No NAT (Bridged / Direct Routing / Pass-Through)
What it does: Network Address Translation is disabled. Network packets pass through the device with their original source and destination IP addresses intact.
NAT is also not a concept in the router’s web UI. The distinction is the auto and custom options in the Select Server 1 dropdown.

Auto / Custom Router Server
The Nano Router connects to a Router Server, chosen under General Settings › Router Server in Select Server 1:

• auto: TVU’s cloud Router Servers. The system selects and allocates one for you, and the address, port, and DNS fields are filled in automatically. The us-east and us-west pin the connection to a specific region.

• custom: a Router Server deployed on your own premises. Enter its Domain Name or IP, Port, and DNS servers, then click Apply.

Cloud Router Servers are provisioned by TVU. An on-premise Router Server is installed and configured together with the TVU support team.

Horizontal Expansion and Remote Backup server support

When Auto is selected on the General Settings > Router Server screen, the system operates in dynamic automatic discovery and routing mode rather than routing traffic to a manually specified static server.

The dropdown has four options, covering two kinds of Router Server:

• auto and the region options (us-east / us-west): TVU’s cloud Router Servers. auto lets the system allocate one; a region option pins the connection there. The Domain / Port / DNS fields are filled in and greyed out, and the button reads Connected.
• custom: a Router Server deployed on the customer’s own premises. The four fields become editable, and the button changes to Apply.

Horizontal Expansion support

• Multi-Unit Clustering & Scaling: The RD300 architecture allows multiple hardware units to be deployed and operate in tandem (horizontal scaling) rather than relying solely on vertical hardware upgrades.
• Capacity & Throughput Expansion: By adding additional RD300 units into a deployment, you can horizontally expand the number of concurrent bonded streams, input/output channels, and aggregate bandwidth across your network infrastructure.
• Centralized Management: When managed through TVU Command Center or centralized routing (TVU Grid / ISX ecosystem), multiple RD300 units can be pooled and assigned dynamic workloads across the cluster.

Remote Backup Server Support

• Redundant Destination Routing: The RD300 supports pairing with a designated remote secondary/backup server (or secondary receiver destination).
• Automatic Failover & High Availability (HA): In the event that the primary server/link experiences degradation, network disconnection, or hardware downtime, transmission streams can fail over to the configured remote backup server with minimal interruption.
• Disaster Recovery / Off-Site Redundancy: Remote backup configurations allow the secondary server to reside in an entirely different physical facility, data center, or cloud region to meet enterprise disaster recovery (DR) requirements.

If the gateway device serving the router fails, it will automatically switch to other available aggregation gateways to ensure the uninterrupted operation of aggregation services.

Turning the Nano Off

After use, complete the following steps to turn the Nano Off:

1. To turn the nano router off when the nano is running in normal mode, press and hold the power button for 5 seconds, then release the button. The device shuts down normally when the indicator light is no longer illuminated.
2. The device may experience an unknown status when running, such as being unable to view the Web interface or the battery having too much capacity. If this occurs, press and hold the power button for 10 seconds to shut down the nano router immediately.

L2-Switch mode

Layer-2 Bridging: Configures physical LAN ports into direct L2 switch mode, passing broadcast and multicast packets across connected segments.

Subnet & Protocol Pass-Through: Essential for broadcast workflows requiring direct local network discovery, NDI, or custom IP protocol passthrough across remote sites.

To configure LAN ports into direct L2-switch mode:

1. Open a web browser and navigate to http://192.168.4.1.
2. Log in with your administrator credentials.
3. Click Advanced Settings and select the L2-Switch tab.

4. To Enable L2-Switch Mode, set the L2-Switch Status toggle switch to ON / Enable. A Caution message appears.
5. If you are confident in your selection, click Turn on, otherwise click Cancel.

6. Select Switch Ports & VLAN Settings:

• Port Member Selection: Check the physical Ethernet ports (e.g., LAN 1, LAN 2, WAN) to include in the Layer 2 switch group.
• VLAN Tagging (Optional): Enable VLAN tagging and specify the VLAN ID (1–4094) if connecting to a tagged trunk port on an upstream/downstream managed switch.
• Spanning Tree / Loop Detection: Enable Loop Protection if connected to redundant external switches.

7. To configure Management IP, select whether the switch interface maintains a local management IP via DHCP or Static IP for accessing the Web UI (192.168.4.1).
8. Click Save or Apply.
9. To verify Switching:

• Plug network cables into the assigned switch ports.
• Verify that downstream devices on different ports can ping each other directly across the Layer 2 network.
