  • How to bypass public IP and NAT
    Firmware's like Asuswrt-Merlin or OpenWRT can support dynamic-dns, or you can do like I do and run something like OPNsense in an x86 VM with a NIC passed through, or buy an inexpensive firewall appliance (up to 500mbps/1gbps/10gbps). Source: 7 months ago
  • Stop ISP from getting into my Router
    The easiest solution is to buy your own router, set it up, disable the router functionality on the Fritzbox 7590 and plug your router into it. It'll be cheaper and easier than a Cisco Firewall, but if you want to go the dedicated firewall route then I would recommenced OPNsense. Source: 7 months ago
  • OpenBSD Innovations
    BSDs may not have a significant presence on desktops, but they're well known in the networking world for their reliability. They also were the foundation used to build OSes for specific applications. OpnSense and XigmaNAS, for example, are two excellent FreeBSD based applications aimed at firewalling/security and NAS/services. https://opnsense.org/ https://xigmanas.com/xnaswp/. - Source: Hacker News / 11 months ago
  • Switches That You Actually Own
    For switches? OpenWrt supports a few models toward the lower end, and SONiC support a bunch at the higher-end datacenter ToR market, but none of these options are SME production-ready like Linux servers or OPNsense firewalls. Source: about 1 year ago
  • Having to pay postage to ship back a DoA product sucks from a customer perspective
    That’s a stupid policy, and it looks like one of my UDMs is defective. I’m an idiot for not just buying good quality open boxes and putting https://opnsense.org/ on them. 🤦🏻‍♂️. Source: about 1 year ago

  • Looking for actually good antivirus.
    Bitdefender and Kaspersky have excellent free offerings. Kaspersky is lightweight. Both updates tend to be seamless. There is no NGAV consumer AV offering in the sense that they don't need constant signature updates like SentinelOne. However, with both solutions I have mentioned I have not seen updates cause crashing. Unless your PC has a hardware issue. Source: 10 months ago
  • “Activation code is invalid for this region” Kaspersky Free AV
    Assuming you've downloaded the correct US software, found here, create a new Kaspersky account, with a different e-mail, install Kaspersky Free, and try activation again. Source: 11 months ago
  • My friend's PC has been hacked/infected
    Download a free AV solution that is known to be effective, Bitdefender or Kaspersky. Source: 11 months ago
  • Should I use Malwarebytes Premium or stick with Windows Defender?
    I would use Bitdefender Free or Kaspersky Free over Windows Defender and Malwarebytes. The free versions of either of these two are more than enough for a personal computer. Defender's local AI/ML engines are unreliable and rely on cloud look ups, heavily dependent on signatures and updates, and can be easily bypassed if you end up running the wrong thing as an admin or have a vulnerability that lets a...
