IP Passthrough is a crucial feature for network configurations requiring direct access to the ISP-assigned IP address. Understanding how does IP Passthrough work in Singapore helps to optimize connectivity by allowing specific devices, such as servers or advanced networking hardware, to bypass the routing functions of a router or modem.

This feature is implemented using DHCP to relay the ISP’s IP and DNS settings to a device or assign a static IP address. The cellular interface typically avoids standard routing protocols in this mode, directing traffic straight between the PPP interface and a specified Ethernet interface.

Configuring IP Passthrough allows a single device to receive the WAN IP address by setting a static LAN port with a designated MAC address. This setup benefits applications that require a consistent internet connection, enhancing network-dependent services’ performance and reliability.


How Does IP Passthrough Work in Singapore? What is IP Passthrough Mode on a Router?

IP Passthrough is a feature that allows one device on a local network to receive the static IP address in Singapore from the Internet Service Provider (ISP). This is useful when a specific device, such as a firewall, server, or computer, needs a direct, unobstructed connection to the internet.

It also offers PAT and NAPT through the same public IP for every host on the private LAN subset. Here’s how does IP Passthrough works:

  1. Direct Connection: IP Passthrough enables the router to connect directly to the ISP’s modem or gateway. This setup bypasses the usual network address translation (NAT) and routing functions the ISP’s device performs.
  2. Unique IP Assignment: The router receives the public IP address, typically assigned to the gateway. This means that the router is exposed directly to the internet with its unique IP rather than behind another layer of NAT.
  3. Improved Network Performance: This configuration is ideal for applications that require a direct internet connection without double NAT environments. It enhances the performance of sensitive applications like VoIP calls and VPN connections by reducing interference and latency when multiple devices perform routine tasks.

How to Set Up IP Passthrough in Singapore [Step by Step Process]

Setting IP Passthrough on a router involves a few concise steps to allow handling the public IP address from your ISP’s modem or gateway. Here’s how to do it efficiently:

1: Access Your Modem or Gateway

  • Connect to Your Network: Use Wi-Fi or an Ethernet cable.
  • Log In: Open a browser, type the modem’s IP address (like 192.168.1.1), and enter the admin username and password.

2: Configure IP Passthrough

  • Navigate to Settings: Find the IP Passthrough, DMZ Plus, or similar section.
  • Set Mode and Select Device: Switch to IP Passthrough mode and select your router, usually by its MAC address.
  • Save and Reboot: Apply changes and restart both devices if necessary.

3: Verify Configuration

  • Check Router’s IP: Log into your router and ensure it displays the public IP on its WAN interface.
  • Test Connectivity: Confirm that the internet is accessible and check the performance of services like VPNs and VoIP.

Why Do I Need the IP Passthrough in Singapore?

Enabling IP Passthrough is strategic for managing network configurations. It facilitates seamless Port Forwarding in Singapore for services like remote desktop access or gaming servers. Look what does IP Passthrough do:

  • Enhanced Control Over Security: IPV4 Passthrough enables direct management of router-based security, allowing for customized firewall rules and intrusion detection.
  • Optimization for VoIP and VPN Applications: It resolves double NAT issues, enhancing the reliability and performance of VoIP and VPN applications.
  • Freedom from ISP Restrictions: Users can freely configure their networks, enabling advanced settings and greater customization without ISP constraints.
  • Efficient Resource Utilization: Removing double NAT improves data flow, reduces latency, and optimizes bandwidth, increasing network efficiency for multiple users and devices.
  • Future-Proofing the Network: IP Passthrough provides a flexible base, supporting the integration of emerging technologies and ensuring network adaptability.

What is a Bridge Mode?

Bridge Mode is a feature on networking devices that simplifies the network by turning a router into a network bridge, which passes network traffic between segments without routing. This mode disables functions like NAT, DHCP, and firewall services, allowing another router to manage these tasks.

It’s useful for expanding a network, improving connectivity, and utilizing features of more advanced routers. Bridge Mode helps integrate different network segments and avoid complications like double NAT issues, making it ideal for enhancing network performance and capabilities.

IP Passthrough vs Bridge Mode – How IP Passthrough Differs from Bridge Mode

Many are confused is IP passthrough the same as bridge mode. However, they serve distinct purposes despite some similarities. While Bridge Mode disables the router functions to prevent IP address conflicts, IP Passthrough allows the router to pass the public IP Address. This means the device takes over some of the roles handled by the router, such as managing the external IP address.


Is IP Passthrough Safe to Use in Singapore? [Disadvantages of IP Passthrough]

IP Passthrough, while advantageous for certain applications and setups, also has several disadvantages that can impact network management and security:

Increased Security Risks

By assigning the public IP address to a device such as a personal router, IP Passthrough exposes that device directly to the internet. This exposure can increase the risk of external attacks if the device’s firewall and security settings are not adequately robust.

Complexity in Network Setup

Configuring IP Passthrough can complicate network setups, especially in environments with multiple routers or complex network architectures. IP Passthrough on or off requires careful configuration to avoid creating network vulnerabilities or performance issues.

Limited IP Addresses

Since IP Passthrough uses the ISP’s public IP address and assigns it to a single device, it limits the ability to distribute public IP addresses across multiple devices. This can be restrictive for businesses or advanced home networks that might require multiple public IPs.

Router Dependency

When using router IP Passthrough, the network depends heavily on the router receiving the public IP. This dependency means the entire network can be impacted if the router fails or experiences issues.

Potential for ISP Compatibility Issues

Not all ISPs support IP Passthrough, and even when they do, there may be specific requirements or restrictions that could complicate its use. Users must ensure compatibility and support from their ISP, which can vary widely.

FAQs: How Does IP Passthrough Work in Singapore

IP Passthrough mode assigns the 4G/3G IP address from the router to a single device on the LAN to use the mobile network’s IP for internet access. This IP facilitates Port Address Translation (PAT) and Network Address and Port Translation (NAPT). The 4G/3G IP assigned is then reused by a computer on the LAN, bypassing standard home routing functions.

Yes, IP Passthrough disables all Wi-Fi on the device passing through the IP. This happens because the device stops functioning as a router, which includes halting the broadcasting of Wi-Fi signals. Once disabled, cellular WiFi passthrough re-enables Wi-Fi, allowing the device to resume router functions and broadcast signals.

IP Passthrough and Port Forwarding are distinct networking functions. IP Passthrough allows a device to bypass the modem’s NAT to handle all routing and firewall tasks, receiving the public IP address. Port Forwarding, meanwhile, directs external internet traffic to a specific device within your private network based on port number, facilitating access to services or applications from outside the local network.

IP Passthrough is limited to one device, which will receive the WAN IP address directly from the ISP. If multiple devices are connected, you can specify which device will receive the WAN IP by configuring a specific MAC address in the router IP passthrough settings.

IP Passthrough enhances gaming by reducing latency, improving connection stability, and achieving a more favorable NAT type for better multiplayer interactions. This setup allows direct communication with game servers for smoother gameplay. However, when using IP passthrough for gaming, ensure robust security measures as the gaming device is exposed to the internet.

IPsec Passthrough facilitates secure IP connections over gateways using Network Address Translation-Traversal (NAT-T), which helps traffic reach its intended destination even when devices lack a public IP address. This method is beneficial for establishing encrypted connections through routers that perform Network Address Translation (NAT). In contrast, traditional NAT modifies the IP address and port information of traffic passing through it, which can interfere with the direct connectivity required by IPsec.

Yes, IP Passthrough can work with static IP addresses. It allows a specified device to use a static public address directly, ensuring it remains accessible at the same IP address.
