How to open ports on Controllino Helium Miner

If you want to open up specific ports on your Controllino Helium Miner, here’s how:

1. Figure out which ports you need to open.
2. Log in to your router and find the port forwarding section.
3. Add the ports you need to open and save your changes.
4. Test to make sure the ports are open.

However, adding Port Forwarding rules is not as easy as it seems. Most ISPs perform CGNAT and prevent users from opening ports.

What is CGNAT

CGNAT is short for Carrier-Grade Network Address Translation. It’s a method that internet service providers (ISPs) use to map multiple public IP addresses to a single private IP address. This helps ISPs conserve IPv4 addresses.

CGNAT is essential because it allows ISPs to continue providing internet service to customers even as the pool of available IPv4 addresses dwindles. CGNAT is also sometimes called large-scale NAT (LSN).

Why can’t I open ports on a router behind CGNAT

If you have a router behind a carrier-grade NAT (CGNAT), you might not be able to open ports on it. That’s because CGNAT usually blocks incoming traffic to private IP addresses.

To fix this, you will need to use a public IP address for your router. You can usually get one from your ISP. Once you have a public IP address, you should be able to open ports on your router without any problems.

If you are still having trouble, you can try using a Port Forwarding add-on from PureVPN. This will allow you to map a public IP address to your router’s private IP address so you can connect to it from anywhere in the world.

How can a Port Forwarding add-on help port forward routers

PureVPN’s Port Forwarding add-on can help port forward routers and get around CGNAT by allowing you to select specific ports you want to keep open. 

This can be useful if trying to access a service usually blocked by your ISP or firewall. By opening the specific port, you can ensure that the traffic is allowed through and that you can access the service. 

Additionally, PureVPN’s Port Forwarding add-on can help get around CGNAT by allowing you to select a different server location. This can be useful if your ISP is blocking traffic from specific areas. Connecting to a server in a different location ensures that your traffic is not blocked. 

Why choose PureVPN

PureVPN is one of the world’s most popular and widely used VPN providers. It offers a fast, reliable, and secure connection that can get around CGNAT. PureVPN has a strict no-log policy, which means your online activity is never tracked or monitored. 

In addition, PureVPN uses AES-256 bit encryption to keep your data safe and secure. Overall, PureVPN is ideal for getting around CGNAT and opening ports on various routers.

PureVPN’s Port Forwarding add-on opens specific ports on your router to allow inbound traffic from the Internet. This will enable you to run applications that require incoming traffic, such as online gaming or video conferencing.

To set up port forwarding, you will need to:

1. Log in to your PureVPN account and go to “Port Forwarding” under “Add-ons.”
2. Select the protocol (UDP or TCP) and enter the port number you want to forward. You can also select a specific IP address or range of IP addresses to forward traffic.
3. Click “Add” to save your changes and then “Apply” to make the changes take effect.

That’s it! Your application should now be able to receive incoming traffic on the specified port.
