ZeroShell Reviews

Best free Linux router and firewall distributions of 2023
Although Zeroshell never reached the point of being good enough to be recommended, we had high hopes for it in 2019 when we started maintaining this list of recommendations because it was developed from scratch rather than based on another system and had some innovative features. Unfortunately, the system got officially abandoned in September 2021. No longer maintained and...

The Hunt For the Ultimate Free Open Source Firewall Distro
Any chance for an overview/update of the top contenders? Your last update was 2015 and we are closing fast on 2020. I'd like to see a revisit of top contenders only - ideally free but feel free to include a commercial version or two if it is really that much better.

  • 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: 4 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: 4 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 / 9 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: 10 months 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: 10 months ago
