FreeBSD Reviews

Best free Linux router and firewall distributions of 2023
OpenBSD and FreeBSD are actively developed and are very capable, but these systems require a high level of understanding of operating system internals and low-level networking to be used as routers.

OPNsense Reviews

Best pfSense Software Alternatives and Competitors
OPNsense is the best open-source and free firewall alternative to pfSense Software. OPNsense is a user-friendly, open-source, FreeBSD firewall and router. Most of the same capabilities are available in this fork of pfSense Software. It distinguishes itself from other firewalls by combining highly sophisticated features with an open-source system. First, the OPNsense firewall...

Its current development pace is rapid, and it’s packed with features. It also has one of the best user interfaces of all of these options. Like a lot of these options, its primary weakness is its Wi-Fi support. A lot of OPNSense users started...

  • I've never used FreeBSD and have some questions
    Aside from being UNIX based, what similarities does it share with Linux? Both have monolithic kernels. Source based build systems are offered (ports, which are like the portage system on Gentoo) as well as binary build systems (pkg, which is like apt, yum, pacman, etc.) Both offer a lot of free software, though more licenses are compatible with FreeBSD like CDDL, which is not compatible Linux. Both let you... Source: 6 months ago
  • FreeBSD turns 30 today!
    There's no mention of a birthday on their site, and its footer says 1995-2023. That must be just the site, because Wikipedia tells me FreeBSD's initial release was indeed, but not quite, 30 years ago, November 1st 1993. Still no birthday. Source: 11 months ago
  • Computer
    I'm not the right person to ask this -- I just run it on whatever I happen to have. But I think sleep and wifi (for example) have issues with different hardware, so you'd have to do your homework. The FreeBSD handbook on freebsd.org is always very helpful to me. You can try it out with a live cd / thumbdrive to see how much supported hardware you've got. My Lenovo X1 from a couple years ago works for what I... Source: 12 months ago

  • 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: 5 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: 5 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 / 10 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: 11 months ago
