Establishing Remote Network Access for Your Starlink Connected Boat


Starlink’s satellite-based internet service has revolutionized connectivity for boaters, offering access to the online world from remote locations. However, a notable challenge with Starlink is the carrier-grade NAT (CGNAT) implementation, which restricts direct internet access to your Starlink antenna. This article delves into the hurdles posed by CGNAT and presents two practical workarounds for establishing remote network access through a VPN.


Starlink’s utilization of CGNAT means that your Starlink antenna doesn’t have a direct public IP address, making traditional methods like setting up a VPN server or enabling port forwarding and DMZ access more complex. This is a departure from conventional internet service providers like cable, fiber, or DSL.


  • Priority and Mobile Priority Service Offer a Public IP Option:
    Starlink provides Priority (also known as Business) and Mobile Priority (Maritime) services, which come with a public IP address. However, these services typically come at a higher cost and are primarily designed for stationary use. Mobile Priority may be suitable for some users, but keep in mind that the assigned IP address can change when traveling globally.
  • Build a VPN-Based Relay with Peplink’s SpeedFusion:
    For users in need of remote network access, regardless of their Starlink plan or location, setting up a VPN-based relay is a robust solution. Peplink’s SpeedFusion VPN with FusionHub is the preferred method for achieving this. Here’s what you need:
    • Replace the Starlink Wi-Fi router with a Peplink Balance or MAX router.
    • Install a FusionHub server in the cloud with a static/public IP address.
    • Establish a SpeedFusion VPN connection from the Peplink router to the FusionHub.
    • Configure port forwarding and/or OpenVPN/IPSEC VPN on the FusionHub.

Once configured, your devices can establish a VPN connection to the FusionHub, providing access to the Starlink network. Post forwarding on the FusionHub can be set up to connect to devices within the Starlink network.

Additional Benefits of SpeedFusion and Peplink for Starlink

Peplink routers and SpeedFusion offer more than just remote access to Starlink. They can enhance connection performance by combining 4G/5G cellular with Starlink or multiple connections, ensuring a more reliable single connection for activities like video and voice calls.


While establishing a VPN directly with your Starlink connection is hindered by its CGNAT implementation, solutions like Peplink’s SpeedFusion VPN with FusionHub bridge the gap, providing remote network access and more. This approach not only enables VPN access but also leverages Peplink’s unique SD-WAN/SpeedFusion technology to enhance your connection’s reliability and performance.
