My current firewall, which also does inter-LAN routing with iptables filtering, has six (6) gigabit Ethernet ports on it (including one 4-port Intel card in a PCIe-x4 slot). Which model Raspberry Pi should I use?
From my experience I would say avoid the 4B if you value stability.
You'd probably want to use USB-Ethernet adaptors. You could have more or less as many as you like. I'm using Ethernet over USB with several little Pi Zeros. No actual physical Ethernet hardware, but a network stack etc. in the applications. The Zero has no Ethernet port at all but some of the things we're running on them expect you to have one. You can comfortably watch movies on the Pi Zero. It's amazing such a tiny thing can do that, at least it is when you're as old as I am and the first CPU youactually handled was a 1MHz (ONE MegaHertz) Motorola 6800, and you had to wear ear defenders for programming it via ASR33. Without knowing more about the performance you'd need I couldn't say whether one Pi or another would do the job, but unless you're a very heavy user of bandwidth I'd be surprised if you'd stress the quad core 1.4 GHz CPU of a Pi 3B+ in a firewall just filtering packets. To be honest, the few times that I've run CPU stats on my firewalls, the CPU usage has been so low that it hasn't really made an impression. I've just checked our perimeter firewall, CPU is hovering about 99.6% idle. As I said this isn't a Pi, it's an ALIX board which is a single-core, 32 bit AMD 'Geode' at 500MHz. Never seen one crash. Straying back somewhere near the topic, I think you'd need the Pi4B with probably 4G of RAM to run clamd or clamscan. I run clamd on one but that's all it does. It crashes occasionally, last time was 6.5 days ago. My money's on power supply problems. I don't think it's temperature related, it was running at about 65C when it crashed last, it redlines at 85C. It's supposed to throttle itself when it gets up there but I haven't any done real stress testing like I have with some other devices. Most of our 4Bs are in at least 50% glazed offices and despite being in England it can get very warm in there sometimes. In summer they're often operating in the 70s without any trouble. We fit the CPUs with heat sinks, but no fan. You might be able to run a local ClamAV mirror with only a Pi 3B+ with its roughly 850M available RAM - I'll give that a try someday. -- 73, Ged. _______________________________________________ clamav-users mailing list clamav-users@lists.clamav.net https://lists.clamav.net/mailman/listinfo/clamav-users Help us build a comprehensive ClamAV guide: https://github.com/vrtadmin/clamav-faq http://www.clamav.net/contact.html#ml
