There are countless occasions when you want to share data between two computers that are not using the same LAN. This case is more particular for gamers that have to intercept data from various devices and are not using a similar network or connection.
In that situation, port forwarding is the only approach remaining for use and is pretty much convenient for users to configure their routers for data tunneling and forwarding.
Port forwarding helps send data to servers, and users don’t have to worry about the complexities of this data transfer to the server since port forwarding works behind the scenes and users will not be aware of whats going on with its data, but the data packet will ultimately reach its destination without any hindrance.
Port forwarding, in simple words, is playing with data packets that are created when users request them over the internet. Using the internet protocol and device ports, that data packet will be linked to an appropriate interface.
This interface will then transmit that data packet to its desired destination that was requested by the user using the information available in the header. To map out all of this process and understands data transmission and porting, continue with the following passages and have an in-depth review of port forwarding and its purposes.
What is Port Forwarding?
Port forwarding is a computer networking term that is used interchangeably with port mapping. Poort forwarding is an extension of network address translation (NAT) and this application of NAT is meant to redirect data from one IP address to a specific port number.
Port forwarding creates a gateway for connecting remote computers over private networks (private LAN). Port forwarding traverses the network communication networks from the internal networks to external networks. That is to say that port forwarding creates abridge between two types of networks using the IP address ( for internal networks) and the port number (for external networks).
Why do we need to port forward?
Port forwarding is required to make the connection of an external computer with your computer using the private network. Port forwarding involves router configuration and feeds it the specific port number that is required to make the connection, or that is intended for the connection.
Port forwarding is a must for external devices to be connected with computers on private networks since external connections are not displayed over private networks. Port forwarding works by port mapping and feeding the specific number of the port.
Port numbers are distinct credentials for each port on every computer, and this feature makes use in port forwarding or TCP/IP port and mapping. TCP ports are designed to recognize an application running on the computer or a device using TCP/IP networking. While the device is identified by the IP address that is specific for each device.
Using different ports, a device with specific IP can run many different services and computer applications. Standard port numbers vary from 0 to 1023, and each port has its distinct number that acts as its identity number.
Is port forwarding dangerous?
Port forwarding involves opening ports that can speed up the connection and improve the gaming performance. That’s why port forwarding very common with gaming users. But the opening port is not entirely secure as it opens a channel for hackers to attack the security and allow room for malware to enter viruses and trojans.
Port forwarding is safe with many devices and dangerous for many devices. The security and safety depend upon the inbuilt firewalls and their strengths to protect against malware attacks. For example, port forwarding Xbox and PlayStation is entirely secure but has low reliability as hackers can attack if not malware and Trojans.
Port forwarding and safe for windows Vista, 7, 8, and 10 due to their inbuilt firewalls that are safe and highly secure for port forwarding. Port forwarding with security cameras is also pretty much safe but has low risks of malware attack, and hackers can penetrate open ports easily.
How To Port Forward Without Router Access
To manually port forward your Nat accessible devices without using the router, follow through the following steps systematically.
- Open the control panel on your computer.
- Go to Network and Internet.
- Open Network and Sharing Center under the Network and Internet options.
- Right-click to locate network management entitled Manage Network and Connections.
- A drop-down menu will display local area connections.
- Right-click on Local Area Connection to locate their properties.
- Click on the properties of the local area connection.
- Properties will open a new dialogue box. Locate sharing and check off the box before it.
- Now locate allow other networks to connect and check the box before it to allow for other users to make a connection with the local area network.
- Now locate allow other network users to control the box and open its settings by right-clicking on it,
- The settings will open a new window before you. Enter the name of the connection with Your IP address and the number of ports to which you want to make a connection.
- Once the IP and Port number are entered, the connection is made after clicking save properties and apply changes.
Enabling port forwarding
To start with port forwarding, users first need to enable port forwarding on their devices. This is a significant step for port forwarding as without configuring the device; users will not be able to run the services on their devices.
To enable the port forwarding to start with configuring a static IP address on your internal device. Then locate a list of available ports on an external network and forward the port number to a specific IP address. In this way, a channel will be created for an internal-external network using –Port connection.
Although it is a simple process to port forward, it requires you to configure your router for the said purpose. The configuration will require admin privileges and after that, you can port forward without using router access.
