  1. The problem is that it varies greatly depending on the router you have. Typical home routers are somewhat limited when it comes to advanced networking features. They may have some of the features, but their implementation may be limited or not very good. See if you can install a 3rd party firmware like DD-WRT or Tomato or similar. That will let you have much more functionality compared to the stock firmware. These projects have many different brands and models they support, so chances are somewhat decent that your router will work. However, doing this does come with an inherent risk of damaging the router if the flashing goes wrong. Its impossible to give an exact guide that works for every single router in the world, because as I said, different manufacturers do things differently. Some routers may not support most of these features.

  2. You use a different subnet that has more IPs available.

  3. To my knowledge, you can't get rid of the gateway. AT&T uses a proprietary authentication method which requires you to use the gateway they provide to you. You can put the gateway in IP Passthrough mode and use your own router if you want. When I had U-Verse years ago, that's what I did. They have a support page somewhere that shows you how to enable IP Passthrough, but they don't offer anymore support or guidance other than what's in the guide.

  4. Not directly. You still need a cable modem. You would plug an ethernet cable from the modem into the WAN port of the router. In the configuration, you can assign which port is WAN and which is LAN. I have Comcast at home and that's how I have my setup.

  5.  @lisagreen3872  You need an ISO file for whatever system you want to install. Once you download it, you add that ISO into the VM's virtual CD drive in the VM's settings.
    2
  6. That's because an OVA file is not a disk image. Its a pre-built virtual machine. You can import it into VirtualBox and that's it; no need to go through the install process. If you want to download the ISO file and go through the install process, you choose the bare metal option.

  7. There are two kinds of IP addresses: Public and private. What you're talking about would just change your private IP address. Your home network has an IP address range so if you renew your DHCP lease, your computer basically asks for another IP address from your router. Usually, you get the same one. On the other hand, your internet provider assigns your router a public IP address. There is no exact way of changing your public IP as it varies between providers. You can usually do a DHCP renew through your router and you may get a new public IP, but you most likely will get the same one.

  8. Of course. The internet hasn't changed much in 2 years.

  9.  @garyhallk494  The irony.
    2
  10. And you're following exactly the steps he's showing? Its hard to troubleshoot these issues without any details.

  11. Larger subnet.
    2
  12. No. VirtualBox is not compatible with M1/M2 Apple chips. There's no current version that support its. I know there's Parallels for Mac that lets you run other operating systems that works on M1/M2, but its not free. And I'm not sure why you would want to disable virtualization. If you want to run VMs, you have to have it enabled. Anyways, Apple doesn't give you any UEFI menu. So even if you had a supported Mac, there's no settings to change.

  13. You can still communicate with other devices on the network via IP addresses. The network switch doesn't understand IP addresses, but it will still forward the frame to the intended destination. This works because the computers and devices all work through the OSI model. Now, without a router, you obviously won't be able to talk to other networks.
    2
  14. You can try it, but I don't think it will work.
    2
  15. VirtualBox is a type 2 hypervisor. That means that it needs an operating system like Windows to be installed so that VirtualBox can work. A type 1 hypverisor is essentially the OS. This would be things like Hyper-V, VMware ESXi, Proxmox, etc.
    2
  16. You would need to use a VPN service on your VM if you want it to have a different IP address. If you turn off your host PC, then everything on it will be turned off, including virtual machines.

  17. I'm not being rude, but is kinda hard to make a video on a very specific provider that doesn't exist in all areas.
    2
  18. He already has one. Its on his channel
    2
  19. That's a private IP address. Completely useless outside of his network.
    2
  20. It doesn't work that way. Your VM has a different private IP compared to the other computers on your network, but it will have the same public IP address since the network traffic to and from the internet still goes through your router.
    2
  21. I strongly suggest watching other videos. NWC is a good presenter but he doesn't go in-depth. You won't learn how to setup a Cisco router or switch just with these videos. Jeremey's IT Lab has a really good CCNA course. He may not be as enthusiastic as NWC, but his course is actually complete.

  22. Anything you connect to your network has the potential for being hacked. This is one of the reasons some people like to create separate networks for IOT style devices or otherwise devices which are suspicious. You can create a subnet and firewall rules that prevent the IOT network from communicating with your main network. There are firewalls that can attempt to identity suspicious network activity occurring inside the network, but those are more advanced to setup and in large networks.

  23. Its generally not preferred to run Kali Linux on your main machine. Its a specialized tool so its best to either run it in a virtual machine or dedicate a computer just for it. You can do it if you really want to, but I wouldn't use it as a main system.
    2
  24. You'll want to use other resources as well. This video series is very far from being complete. There is still a lot of information he hasn't covered.
    2
  25. No.
    2
  26. Windows is a large system. You can try running disk clean up in the virtual Windows system to try to reclaim space. Ideally , you want to give your VM more space; I'd say at least 120 GB.
    2
  27. No... this has nothing to do with command prompt.
    2
  28. CPU and RAM usage only applies when you have the virtual machine running. The storage space, though, is still used up whether or not the virtual system is running.
    2
  29. You can kind of think of the type-1 hypervisor as the operating system. If you install ESXi on a computer, ESXi is essentially the OS. You can then create virtual machines from the hypervisor (usually through a web interface).

  30. I wouldn't worry about the HTTPS warning. In short, you're getting that error message because the certificate that Proxmox has isn't listed in your computer's security settings. So your browser throws up that error as a precaution. Since its your own computers, you don't have to worry about it. If you're a complete noob, its going to be difficult explaining how SSL certificates work and how you can obtain a valid one from a service like Let's Encrypt....

  31. The exam costs $300... not cheap. I would suggest using other sources to study. Network Chuck is a good presenter, but this video series is extremely incomplete. I suggest watching Jeremy's IT Lab. He's not as entertaining as NWC, but his training series is actually complete.

  32. You just delete the virtual machine. Right click on the VM entry, and choose "Remove"
    2
  33. You have to install the virtual box guest additions. This will install the video drive which in turn will let you adjust the resolution and get a full screen. Since you're doing this on Linux, you can usually run a system update on the VM; that should download the drivers.
    2
  34.  @jenlea989  Open a terminal window and type in: sudo apt-get update && sudo apt-get upgrade This will check for any package updates (apt-get update) and then will download install the latest versions of any packages available (apt-get upgrade). Just be advised it may take a while, 10+ minutes and the vm may appear to freeze at times.
    2
  35. It may be that your router or ISP is blocking ping requests on your public IP address.
    2
  36. Yeah good luck dude. You're not going to "hack" gmail anytime soon. If you can't get to your Google account, you're out of luck.

  37. By default, no. There is no ChromeOS version of VBox that I'm aware of. You will need to enable Linux desktop support to try to get this to work. And even then, it probably won't work too well. Chromebooks usually don't have very good hardware so running a VM will probably be a painfully slow experience.
    2
  38. You may need to install the virtualbox guest additions. This contains the drivers which allow for proper resolution and scaling. The exact steps depend on the Linux distro you have installed.
    2
  39. I'm no expert, but if your old PC is too old, it likely would make no sense trying to do cryptomining especially in a virtual environment.
    2
  40. The only thing that is not freed up is storage. If your vm takes up 50 GB of space, it will continue to take up that much space regardless of it being powered on or not.
    2
  41. There will be some performance loss in running VMs. You probably won't notice much loss for web browsing and watching youtube videos.
    2
  42. If the VM is turned off, it won't be using any RAM or CPU.
    2
  43. You can but performance may not be that good depending on the VM and USB version you're using.

  44.  @HackerDoge  Windows 10 is the operating system, not the edition. There is Windows 10 Home, Pro, Education, Enterprise, etc.

  45. IT is a very vast field. For typical IT, you don't need to know any programming. Scripting is useful for admin-level jobs like to automate things (account creation, etc) but you don't need to understand programming to be a systems admin. If you want to go into computer programming, then yes but that is a different realm of IT.

  46.  @hntrains2  Yep. Exactly why I bought my own modem for about $80. I re-used my router that I bought about 2 years prior to that which cost me about $110.
    2
  47. Of course dude. You can install practically any OS in a virtual machine.
    2
  48. And your questions is???

  49.  @thoughtsbright7928  As long as it isn't overheating, it will be fine.

  50. Subnetting is used to break a network into small networks (subnets). You need to understand the math behind this (decimal to binary) to understand how subnets work as well as IPv4 addresses in general. Each network has 2 main important parts: Network address (1st IP address in the subnet) and the broadcast address (last IP address in the subnet). There are several methods used to figure this information out.
