The Network Security Engineer course is a gateway to enter the rewarding field of information technology. This course provides expertise on Kali Linux, Installing Metasploitable, Information Gathering, Network Sniffing, Wireless Hacking and security, and more.





By Default, our firewall and router block incoming connection from external network by blocking ports on our computer in order to secure our device from threats over internet.
In this post, i will show you how to port forward without router.
We need port forwarding in hacking to hack devices over WAN or Internet in Kali Linux or whatever operating system you are using for hacking.
For Example – You are hacking android Smartphone over internet (not in the same wifi network), so you need to open or forward certain ports in firewall or router.
How To Port Forward Without Router

Welcome to Techohalic, In This Article you are going to learn about How to change Mac Address.
When it comes to networking, then most of us probably heard of MAC addresses.
What is it used for?
What is the MAC address?MAC address stands for Media Access Control address.
It is a unique, physical, and permanent address that is assigned to network interface devices by their manufacturers.
So, whether it is your wireless card or ethernet card, each one of these comes with a permanent, physical and unique address, known as Mac address.

Whenever you first open your laptop and your card is just working like normal you know you're just at some coffee shop getting online your card is in something called managed mode and if you type IW config you can see that your card is in managed mode.
So what this means is any data that's coming in my card if that data is not meant for me then the WIFI card is going to ignore it, now 99% of time that's awesome because we really don't care about anyone's traffic.
But before even get started just make sure first that your interface card is up whatever one you want to switch, before we try to swap it over we should probably make sure that airmon-ng can detect our card.
Note: here's a problem that you guys may have a lot of people switch over the card and it's fine and then after a while, it turns back into managed normal mode and they're like what the heck I didn't press anything, what's going on?
So if you as an example, want to send de-authentication messages to knock a client off a wifi network, if you want to capture the four-way handshake if you want to run a rogue access point, your wifi adapter needs to support, monitor an injection mode, and often the wifi adapters in laptops don't support those modes.
Another problem is that a lot of us will run Kali Linux or Parrot OS or something else within a virtual machine.
