What is IP Passthrough? A Comprehensive Guide to Jincan Network’s Industrial Router

Introduction: The Importance of IP Passthrough in Modern Networking

In the era of rapid technological advancements, IP Passthrough has become an essential feature in modern networking, especially in industrial and IoT (Internet of Things) environments. This technology allows devices to directly obtain a public IP address from a Wide Area Network (WAN), simplifying network configurations and enhancing performance.

Jincan Network (https://jincan.net) is a leading provider of industrial communication solutions, offering a wide range of products, including 4G/5G industrial routers, embedded routers, DTU terminals, and IoT gateways. With support for IP Passthrough, Jincan Network’s industrial routers empower businesses to optimize their network performance efficiently.

Section 1: What is IP Passthrough?

IP Passthrough is a networking feature that enables a router to assign its public IP address directly to a device connected to its Local Area Network (LAN). This feature effectively bypasses the router’s traditional routing functions, allowing the device to communicate directly with the WAN.

1. How It Works
   When IP Passthrough is enabled, the router dynamically assigns its WAN IP address to a LAN-connected device (e.g., a computer or downstream router) via DHCP. The router’s other functions, such as NAT (Network Address Translation), are disabled, ensuring a direct connection to the internet.
2. Difference Between Port Forwarding and IP Passthrough
   • Port Forwarding: Requires manual configuration to map specific ports to devices, which can be complex and time-consuming.
   • IP Passthrough: Automatically assigns the WAN IP, providing a seamless and efficient connection.
3. Key Benefits
   • Simplifies network configuration.
   • Enhances performance for devices requiring direct public IP access.
   • Reduces latency and potential network conflicts.

Section 2: Use Cases for IP Passthrough

IP Passthrough is widely used in scenarios requiring direct WAN IP access. Below are some common applications:

1. Industrial Automation
   In industrial settings, machines and controllers often need to communicate directly with cloud servers. IP Passthrough ensures a stable and efficient connection for real-time data exchange.
2. Smart Cities
   Applications like video surveillance and environmental monitoring require fast and secure data transmission. IP Passthrough enables seamless communication with cloud platforms.
3. Corporate Network Optimization
   Small and medium-sized businesses can use IP Passthrough to simplify multi-router setups, reducing network complexity and improving performance.
4. Remote Work and VPN Access
   By assigning a public IP to remote devices, IP Passthrough facilitates secure VPN connections for remote workers.
5. IoT Device Integration
   IoT devices often rely on direct internet access for optimal performance. IP Passthrough eliminates the need for complex NAT configurations, improving connectivity.

Section 3: Jincan Network’s Industrial Routers and IP Passthrough

Jincan Network’s industrial routers (https://jincan.net) support IP Passthrough, providing a reliable solution for businesses. Here’s a detailed look at their features and configuration process:

1. Key Features
   • Dynamic IP Assignment: Automatically assigns 4G/5G WAN IP addresses to LAN devices.
   • Protocol Support: Compatible with PAT (Port Address Translation) and NAPT (Network Address and Port Translation).
   • Broad Compatibility: Works with various devices, including computers, firewalls, and downstream routers.
2. Configuration Guide
   Follow these steps to enable IP Passthrough on a Jincan Network industrial router:
   • Access the router’s web interface and enable the IP Passthrough feature.
   • Ensure the LAN device is set to DHCP mode to receive the IP address dynamically.
   • Once the LAN device obtains the WAN IP, the router’s admin interface will no longer be accessible. Configure all necessary settings beforehand.
   • For downstream routers, transfer all local connections to avoid conflicts.
3. Best Practices
   • Pre-configuration: Complete all necessary router settings before enabling IP Passthrough.
   • Address Conflict Management: Avoid running multiple DHCP services simultaneously.
   • Security Measures: Use firewalls and VPNs to secure devices with direct WAN access.
