Social recommendations and mentions

We have tracked the following product recommendations or mentions on various public social media platforms and blogs. They can help you see what people think about OPNsense and what they use it for.
  • 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
  • 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: 11 months ago
  • Router for a 1.5Gbps connection
    One option is Firewalla Gold Plus, or you could buy a mini PC like it and run pfSense/OPNsense yourself. Source: 11 months ago
  • Looking for Recommendations
    Another option is Firewalla, or buy a mini PC like it and run pfSense/OPNsense yourself. Two similar concepts, with the cost being either money or your DIY time. A lot of Firewalla users say that it's much easier for home use than pfSense/OPNsense, so you might find it worthwhile to spend a little more on it upfront and have to tinker less. Source: 11 months ago
  • Where to start
    VPN or Zero Trust networking + separate users + sophisticated passwords for remote access. Don't expose anything to the web. You can install something like OpnSense (https://opnsense.org/) and configure WireGuard VPN and configure remote access to the services via VPN. Source: 11 months ago
  • Bi-Weekly /r/Technology Tech Support / General Discussion Thread. Have you a tech question or want to discuss tech?
    For most router issues, I recommend people always put them in to dumb bridge mode and put a proper firewall like pfsense or opnsense as your gateway. Source: 11 months ago
  • VPN for network filtering
    If you want firewall, I think you can use https://www.pfsense.org/ or https://opnsense.org/ , maybe running on an old PC or a Raspberry Pi. Not sure. Source: 11 months ago
  • Looking for Guidance and Advice
    I've recently started using OPNsense. It's similar to pfSense, but seems to be considered a little more user-friendly. Source: 11 months ago
  • Learn from my newbie mistakes
    First of all; understand what it is the software you want to use actually does. I know that Proxmox is a Hypervisor and can run multiple VMs (Virtual Machines) and LXCs (Linux Containers) which is great, but there are a lot of options for setting up these things. For example, I really liked the idea of having my router be a VM that ran OpnSense so that I can run multiple router-specific things on the same machine... Source: 11 months ago
  • Ideas to setup for homelab?
    If you are going to apply for WSA, learn Hyper-V, maybe failover clustering (nested) with something like S2D (https://learn.microsoft.com/en-us/azure-stack/hci/concepts/storage-spaces-direct-overview) or starwinds vsan (https://www.starwindsoftware.com/vsan), PowerShell, and automatization with PowerShell. Even all full Windows systems are pretty often deployed on ESXi, so you can learn it. SCVMM, SCOM, and other... Source: 12 months ago
  • Futureproof Router + AP combo?
    You might look into using OPNsense on a small PC with whatever NICs you like for wired routing, with a separate AP and switch. It'll probably cost a little more initially, but it makes it a lot easier to get the exact specs you want, as well as upgrading only the parts that need it. Need a faster LAN? Upgrade the switch. New Wi-Fi standard? Upgrade the AP. Faster internet service? Upgrade the router's NICs.... Source: 12 months ago
  • Weird Situation
    I guess you need a router with a WAN to access the internet. If so, purchase another router, and configure it as a wireless bridge with your primary, or turn one PC into a router by installing something like OpnSense (https://opnsense.org/), add a wireless card, and add a simple switch to connect all your computers to the same switch, configure OpnSense in the way that WAN network is your wireless connection and... Source: 12 months ago
  • Looking for replacement router suggestions.....
    I would look into OPNsense, which is free, community supported, rather advanced, but fairly easy to configure and maintain. You run it on a PC with more than one Ethernet port. Source: 12 months ago
  • Internet connection in germany
    Currently, I use a custom OPNsense router with three gateways: Vodafone Cable, DSL with O2, and a backup cellular connection with O2, as well as another personal phone as a secondary backup with Vodafone. However, I don't recommend this approach due to the complexity of DSL Lite, dual-stack, IPv6 prefixes and the difficulty in obtaining basic information for proper setup from these companies. Source: 12 months ago
  • Is DD-wrt worth it?
    You have options such as PfSense, OpnSense, Arista Untangle and Sophos. I'm sure there are other alternatives as well. Source: about 1 year ago
  • Sophos UTM 110/120
    I see these for sale on eBay (e.g. Pfsense four-port Gigabit router/firewall on Sophos UTM 110/120 hardware) with pfSense installed, so this apparently is an option. OPNsense, a fork of pfSense, may work as well. Both pfSense and OPNsense are based on FreeBSD (UNIX) and are free, enterprise-class, router/firewall software. Both also have attractive, easy-to-use web UIs. For 25€, it may be worth trying it as... Source: about 1 year ago
  • Need to adjust ACL for VLAN,
    Https://opnsense.org/ is a great (and free) choice among others when it comes to SPI-based firewall (opnsense do have IDS and IPS-features aswell). Source: about 1 year ago
  • I thought I didn't need beginner certs?
    A customizable router/firewall. You can set this up on an old computer that has at least 2 physical NICs. PFSense has a free community version and OPNSense is completely free. OPNSense started as a fork of PFSense when some contributers didn't like the way PFSense seemed to be headed. That happened long enough ago that they're pretty different nowdays.
