Hi,
I'm currently using m0n0wall on 833mhz cpu, 512mb ram, 20gb hdd (I know m0n0wall can run on much lower specs).
I don't intend to use the same for OPNsense so my question is what is the minimum hardware for optimum perfomance.
Before I saw this I was thinking of trying pfsense because of its packages support and multi wan, so does OPNsense have support for multi wan and packages like squid proxy?
Regards
Cosmas.
Hi there,
QuoteHardware requirements *
Besides purchasing a ready to go system from a partner you can also install OPNsense yourself to test or run on the hardware of choice.
OPNsense can be installed on 64bit architecture based hardware. There is a minimum specification to run the full firewall functionality and a recommended specification for the complete set of features.
Minimum hardware requirements
Every feature is functional, but perhaps not with a lot of users or high loads.
1GHz dual core cpu
1 GB RAM
40GB SSD
Serial console or video
Recommended hardware requirements
Every feature is functional and fits most use cases.
1.5GHz multi core cpu
4 GB RAM
120GB SSD
Serial console or video

I bet that you can get away with way lower specs, depending on your usage scenario and the needed features.
The specs should get you going, don't worry.
Multi-WAN is available, but may need some restructuring work. Proxy support will be added as we approach 15.7 in June/July.
You should definitely check out pfSense as well. We tend to keep an open mind. Whatever works for you works. :)
I really don't get the "official" hardware requirement (https://wiki.opnsense.org/manual/hardware.html (https://wiki.opnsense.org/manual/hardware.html))
I just made a harddisk installation of 18.1:
Mem usage: 147MB
HDD usage: 1,3G
40G of HDD??? I assume that is only if you need to save A LOT of log data, right?

I also use OPNsense on rather old and low-end hw. And it is working fine for my requirements as a firewall! :)
But if you want to use modules like Proxy, AV, IDS/IPS, etc. and/or have a lot users you need much more ressources.
And remeber. It is 2018 and i.e. a PC-Engines APU2-Kit offers the OPNsense minimum hw requirements for < 200€! ;)

I'm running it as VM on KVM, that's why ressources matter more than on physical hardware.
I don't know about your network and number of clients, I don't know about which particular functions on OPNsense (base + plugins) you intend to use either, but I'd suggest you to configure your VM like:
1. CPU: 2 cores
2. RAM: 1 GB
3. Storage: < 5 GB.
It will do for FW, NAT, DHCP, DNS - DNSMask/ Unbound etc.
If you plan to add web proxy (forward), ha-proxy (reverse), IDS/ IPS etc etc etc then you will definitely need (much) more
