How to Port Forward Hyperoptic and Bypass CGNAT

Hyperoptic routers require you to forward specific ports to communicate with external devices or game servers. From client servers to online games and P2P applications, you have to allow access to your network to receive incoming requests. But, some ISPs perform CGNAT, which can cause complications when you are trying to forward ports on these routers. Here is a detailed guide to help you get around CGNAT and open ports behind a Hyperoptic router.

What is CGNAT?

CGNAT (Carrier-grade NAT) is a technique that conserves the depleting IPv4 pool. This address translation mechanism introduces a new layer of IPs to the conventional method of translating IPv4 addresses. With CGNAT in place, most ISPs allot the same public IP address to different consumers relying on the same internet network. 

Issues Hyperoptic Users Face Due to CGNAT

Hyperoptic users are likely to experience the following issues if their connection is behind CGNAT:

• Port Forwarding Limitations: CGNAT assigns a shared public IP to multiple users, making it nearly impossible to set up port forwarding. This prevents external users from accessing home servers, security cameras, and other remote devices. 

• Online Gaming Problems: With CGNAT, gamers experience increased latency and instability, causing high ping rates, lag spikes, and disconnections, which impact the overall gaming experience. 

• Server Hosting Hurdles: CGNAT prevents users from hosting web or game servers by stopping incoming connections by default, making it challenging to allow external access to personal servers. 

VoIP Quality Challenges: CGNAT complicates VoIP services, adding latency and causing packet loss that reduces call quality, resulting in delays and drops during calls due to compromised direct IP connections.

Why does Hyperoptic perform CGNAT?

Without CGNAT, ISPs must continuously invest money to get more usable IPv4 addresses because the depleting IP pool enhances the cost. With CGNAT, ISPs can reduce the number of allocated IP addresses by assigning the same public IP to different customers on the same network. 

Opening ports behind CGNAT is risky, even if your Hyperoptic router is configured for port forwarding. You can get your IP blacklisted if you try to port forward on a shared IP address, primarily when your ISP performs CGNAT. However, using a port forwarding add-on can help you with this problem.

Frequently Asked Questions

Does Hyperoptic use CGNAT?

Yes, Hyperoptic uses CGNAT due to the limited availability of IPv4 addresses. This technique allows the ISP to extend its IPv4 address pool and efficiently manage network resources.

Can I opt out of Hyperoptic CGNAT?

You can, but only if you purchase a static IP address from Hyperoptic—this will cost you an additional fee.

What is the best Hyperoptic CGNAT workaround?

If you are a Hyperoptic customer and looking to get around CGNAT, a port forwarding VPN like PureVPN can be an effective workaround. It allows you to route specific traffic directly to your device, circumventing the limitations imposed by CGNAT.
