    Yes that is true, I may do a video explaining that in the future it can effect it very bad or just simply delay it, but yes the more obstacles, the slower. If everything is absolutely pristine and set up correct then it should effect it much.

    sometimes its better to have 2 or more firewalls for better security. I might experiment with a virtual firewall and see how well it goes.

    Do I need a network firewall with my McAfee firewall for my home? Recently I had to buy a new wifi router & couldn't get my printer to print & when I called in I was told I had a trojan & there were 7,241 attempts from out of the country & they were causing my network problems. I was told I needed to buy some kind of software & technical support that included:
    1) Printer wi-fi setup
    2) System update and cleanup
    3) Internet security with anti ransomeware firewall.
    4) Technical support by Geeks Core Solutions.
    This is supposed to be good for 2 years. Should I look into getting a hardware firewall for after this lapses?

      Great explanation about firewall. Really information. Firewall is the basic necessity security software you always wanted for your PC. I have Comodo Personal Firewall into my PC i.e. personalfirewall.comodo.com/. Very clearly been elaborated on why we need firewall.

    Your rack sounds very loud. Are they old? . . and where do hardware and software firewalls differ if the hardware firewall also have software? . . . ive setup a 1u rackmount server and installed iptables . . so is it now hardware firewall?

  • @at54tl

    Yes, The more obstacles data has to journey. The slower it gets to its destination . Unless using like high end enterprise equipment and its finely tuned to optimal performance.

    hardware firewall will not make your network 100% secure nothing is 100% secure there is always vulnerability

    Very important to have a software firewall in addition to a hardware one. A hardware firewall will prevent access from the internet, a software one will prevent unauthorized software from accessing the internet from your machine. A common thing for malicious software to do (probably the biggest pc vulnerability). Of course a software firewall is only as good as the person who uses it. Some people will put it on, then over ride it. To get good results, it may be inconvenient at first and takes some set up.
    I would get something better than windows firewall as malicious software will likely add it's own exception defeating it, but still better than nothing.
