The easiest example to illustrate the port forwarding concept is that of a simple web server.Ī web server needs to accept incoming connections from the internet – typically on ports 80 (HTTP) and 443 (HTTPS).

With that said, let’s talk about opening some! ? Example – A simple web server Open or forwarded ports are the most common attack vectors for a network, so you will want to keep as many closed as possible. The act of poking (the right kind of) ‘port’ holes in the firewall to permit certain kinds of traffic from the internet through the firewall via those ports, and through to a specific device on your network like your Helium miner/hotspot.

It’s also there to BLOCK nasties from the Internet coming into your network through open ports. The (very simplified) purpose of a firewall is to ALLOW devices from within your network to safely make connections out to devices and services on the internet. Routers typically have some kind of inbuilt firewall. HTTP (used for browsing) operates on port 80, HTTPS (used for secure browsing) uses port 443, and FTP runs over port 20 or 21, etc, etc, etc.Īccording to Helium’s security doco, Helium hotspots communicate with their peers across the internet on TCP port: 44158. In fact, there are 65,535 ports that can be used for communication in TCP/IP.ĭifferent ports are used for different network protocols and the first thousand or so are reserved for specific applications. Ports and Routers/Firewallsĭevices on the internet communicate with each other over different ‘ports’. There are thousands of different routers and an equal number of ways to set up port forwarding on those devices, so this is NOT a how-to guide! This guide instead, is intended to explain port forwarding a little so it’s better understood, and to give you a few resources to follow to try and organise it for yourself – if you need to. It's most suitable for advanced users, with no integrated help file, but the simple design lets you quickly find your way around.You may have heard that setting up port forwarding is beneficial in certain situations where your Helium Miner/Hotspot is ‘relayed’, and you are probably wondering what that means, what port forwarding is, and how you might go about it… In conclusionĪll in all, Smart Port Forwarding provides a straightforward solution to forwarding multiple ports. We have not come across any issues throughout our evaluation, as the tool did not hang or crash. The program barely uses CPU and RAM, so it doesn't affect overall performance or interrupt user activity. During an active process, the primary panel shows the protocol type, listened address and location to forward it to, type, and running status. Last but not least, Smart Port Forwarding lets you establish a default forwarding path, in case all rules fail or none are entered. It is possible to create as many rules as you want. Forward ports by multiple rulesĪdding a new rule implies pointing out a rule name, search type (hex or text) and data type, along with an IP address and port number to send data to.
REVIEW PORT FORWARD UTILITIES WINDOWS
It's possible to make it run with Windows so it's ready when you reach the desktop. Note that it minimizes to the tray area on launch, but you can easily identify it through the icon and bring up the configuration panel. Once you specify a protocol (TCP or UDP) and listening port, you can enable Smart Port Forwarding to capture the first packet to a LOG file, and establish forwarding rules. Easy setup process and light interfaceĪfter a brief and uneventful setup procedure, you are greeted by a standard window with a plain layout, where you can add a new forwarding port through the context menu. It mainly targets advanced users, such as network administrators. Smart Port Forwarding is a simple-to-use application designed for forwarding multiple ports, as the name suggests. Some environments might require advanced network settings to be done in order to be able to share files or even grant access to the Internet.
