Review: Very capable little firewall box - Have this running as a OPNSense firewall for the house. More than capable of gigabit throughput even with ad blocking and basic IPS. Would advise running the firewall as a Virtual Machine on Proxmox though rather than bare metal. Originally had it bare metal as was concerned about losing performance but discovered yesterday that there's a hardware/driver bug with the Intel NIC that completely kills PPPoE throuput. Got to spend last night rebuilding it all as a VM to work around the problem 😴. However I can now confirm that there's no noticeable drop in performance when running as a VM and can now easily get 900Mb/s throuput on both of my internet connections. Only recommendation would be to consider upping the RAM to 16Gb instead of 8. Still working fine but it's a little bit tighter than I'd like once Proxmox takes 2GB for itself.
Review: STRHIGP Firewall Mini PC works well with pfsense - This review relates to my purchase of the fanless STRHIGP firewall mini pc with 4 network ports, 8GB RAM, 120GB SSD and RS232 serial comm/console port. It is worth noting that the four NICs are Intel based which is important for my use case. I purchased this device with the intention of installing and configuring pfsense v22.05 as a backup router/firewall for my Netgate WAN router. The spec of this purchase is somewhat overkill for pfsense, but this was intentional in case I needed to repurpose the device. The install went smoothly. Using the RS232 port & 'PUTTY' app on my laptop, the console monitor worked perfectly. I accessed the pfsense webgui via my laptop browser to complete the detailed configuration of the router. Note that there may be compatibility issues with pfsense and the built-in wireless adapter, but for me I don’t require this function. So far I am very happy with my purchase, especially as the price & spec of the STRHIGP router is favourable compared to other equivalent hardware options. I have been in contact with STRHIGP customer support on a couple of occasions & received prompt responses each time. Finally, customer support confirms the unit has a 3 year warranty although I'm not sure how the return process works. The only negative is the lack of detailed hardware documentation or a dedicated website.
