Currently, Starlink doesn’t support port forwarding. However, Starlink port forwarding is still possible, which we will learn later in the article. For now, let’s discuss a few important things.

Port forwarding is a way to allow computers on the internet to connect to a specific computer or service within a private local network.

It works by setting up a rule in your router that directs traffic to a specific port to a specific device inside your network.

This is often used for running web servers, gaming servers, or other services that need access from outside your home or business network.

Since Starlink doesn’t support Port Forwarding, users can’t set up these types of direct connections using their Starlink internet service.

What is CGNAT and How Do I Bypass It?

Carrier Grade Network Address Translation (CGNAT) is a technology ISPs use to extend IPv4’s lifespan by allowing multiple subscribers to share a single IP address.

While cost-effective for ISPs, it complicates direct device access due to blocked inbound ports under Starlink’s default CGNAT policy.

In the case of Starlink, both CGNAT and Port forwarding go hand in hand. Starlink employs Carrier-Grade NAT (CGNAT) to manage IP address allocation by assigning multiple subscribers to a single public IP address.

This architecture complicates traditional port forwarding, as incoming packets cannot be routed to specific internal devices without unique external IP addresses.

To bypass Starlink CGNAT limitations, customers can employ a VPN service.

A VPN can help bypass the limitations of Starlink’s CGNAT by establishing a secure tunnel from your device to a VPN server with a unique public IP address.

This makes your internet traffic appear to be coming from the VPN server instead of through Starlink’s shared IP.

Additionally, some VPN services offer port forwarding, which allows external connections to reach your device via specific ports on the VPN server.

Apart from VPN, if your mobile network isn’t under CGNAT, you can connect your mobile phone to your Starlink router and use it as a hotspot.

Challenges of Starlink Port Forwarding

Challenges of Starlink Port Forwarding
Starlink Port Forwarding

Port forwarding enables remote access to services on a local network. It typically involves configuring a router to direct internet traffic to specific devices. However, implementing port forwarding on Starlink presents unique challenges.

Port forwarding is essential for remote access to services hosted on a local network, where a router is configured to direct incoming internet traffic to specific devices. However, implementing this on Starlink involves several unique challenges:

Security Risks

Opening ports through port forwarding can make your network visible and accessible from the Internet, increasing vulnerability.

Hackers actively scan for open ports to exploit, potentially gaining unauthorized access to your systems and sensitive data. This risk necessitates robust security measures, like firewalls and secure passwords, to protect exposed services.

Starlink-specific Configuration Issues

Starlink’s use of Carrier-Grade NAT means users do not have unique public IP addresses. Instead, many users share a single IP address.

This setup makes traditional port forwarding nearly impossible. Incoming traffic to a shared IP cannot be routed to a specific user’s device without additional configuration, requiring alternative methods or ISP intervention for direct external access.

Remote Access Complexity

Starlink typically assigns dynamic IP addresses that can change over time. This variability makes it difficult to maintain stable remote access because the IP changes require frequent updates to the port forwarding configuration.

Users must continuously monitor and update their settings to ensure remote access remains operational.

How To Perform Starlink Port Forwarding

Although Starlink does not support port forwarding, customers can still port forward by connecting a third-party supported router.

Here are the steps to Starlink Port Forwarding.

Identify your Starlink Terminal

Identify your Starlink Terminal

Please note that Starlink offers two generations of hardware for home users: the Gen-1 Terminal (Round Dish) and the Gen-2 Terminal (Rectangular Dish).

The primary difference between these versions is the presence or absence of an Ethernet Jack. The Gen-1 terminal has an Ethernet jack, whereas Gen-2 does not.

Check Router Compatibility

Ensure your third-party router supports port forwarding and can handle dynamic IP addresses via DHCP.

Connect the Third Party Router

Here are the steps to connect a third-party router to Gen-1 and Gen-2 terminals.

Follow the steps if You have a Gen-1 Starlink Terminal

Gen 1 Starlink Port Forwarding

The original Gen-1 Terminal features a round dish equipped with an Ethernet Jack. Since the standard Starlink Router does not support Bypass Mode, it must be disconnected if you want the third-party router to serve as the primary router. Configure your network as follows:

  • Disconnect the Starlink Router by removing the cable connected to the power supply.
  • Connect the Starlink PoE (Power over Ethernet) Adapter to the WAN port of the third-party router.

Follow the steps if You have a Gen-2 Starlink Terminal

The Gen-2 Terminal, characterized by its rectangular dish, does not include a PoE adapter. For this version, an Ethernet Adapter must be purchased from Starlink for router connection.

After linking the Starlink Terminal to the Starlink Router:-

  • Attach the third-party router’s WAN Port to the Starlink Ethernet Adapter.
  • To designate the third-party router as the main network router, activate “Bypass Mode” on the Starlink Gen-2 via the Starlink App. If you see Starlink No Active Account contact customer care to resolve the issue.

Activating Bypass Mode will turn off all wireless features on the Starlink Terminal, and a factory reset is needed to revert to the original router mode.

Note: “Bypass Mode” specifically allows third-party routers to handle network traffic and is not a feature for enabling port forwarding on the Starlink router itself.

Set Up Port Forwarding on Your Router

Once your third-party router is connected, follow the steps below.

  • Log into your router’s administration interface. This is usually done through a web browser using an IP address like or
  • Look in the router settings for the port forwarding section. It could be under tabs like “Advanced,” “Port Forwarding,” “NAT,” or “Applications.”
  • Enter the specific ports you need to forward and specify the local IP address of the device that requires external access. This device could be a server, a gaming console, or a security camera.
  • Save the settings and test the configuration to ensure the ports are forwarded correctly. You can use online tools to check if the ports are open.

Verify and Test Connection

Check the WAN IP address in your router’s admin panel to confirm it receives an IP from Starlink.

In addition, tools like port checkers should be used to ensure that the intended ports are open and to direct traffic to the correct internal IP address.

Alternatives to Starlink Port Forwarding

While port forwarding is a common method for remote device access over the Internet, some users may seek alternatives for enhanced security due to limitations with Starlink’s use of CGNAT. Below, you will find a brief examination of potential options.

Virtual Private Network (VPN)

A VPN allows the extension of a private network across the public internet, enabling you to send and receive data as if your devices were directly connected to the private network. Establishing a VPN server bypasses the need for port forwarding by directing all traffic through a secure tunnel.

  • Step 1: Obtain services from a reputable VPN provider that supports port forwarding.
  • Step 2: Install the VPN software on the relevant device.
  • Step 3: Configure the VPN to permit port forwarding if necessary.

Mesh System

You might consider setting up a mesh network system to improve local network coverage rather than enable remote access.

These systems provide extensive Wi-Fi coverage and usually have advanced router features that simplify network management.

Unlike traditional routers that broadcast Wi-Fi from a single point, mesh systems use multiple access points, or ‘nodes,’ to create a seamless and robust Wi-Fi network.

Each node communicates with the others, creating a cohesive network covering every corner of your space.

Installation is straightforward, and many mesh systems offer user-friendly apps that guide you through the setup and allow you to manage your network effortlessly.

Adopting a mesh network ensures a stable and consistent internet experience.

For users aiming to bypass limitations like CGNAT, replacing port forwarding with a service such as a VPN can be an effective method.

Additionally, incorporating an advanced router or mesh system may enhance local network management without directly affecting remote access capabilities.
