Questions on a new pfSense build - i5 7400, ASRock H270M-ITX/ac
-
I have heard Wifi is… sketchy... on pfSense? Or at least, it takes more processing power....
It's more that wifi hardware support is sketchy on FreeBSD generally than pfSense specifically. I've used pfSense as an AP in the distant past (with 802.11g hardware), so theoretically it is capable as far as the software is concerned, given well-supported wireless NICs. Those are hard or impossible to find (especially in the AC realm). Add into that physical placement of the antennas. You're always better off having your radio close to the antennas (no excess coax cable carrying high frequency RF), and since the antennas are ideally situated outside of any cabinet, preferably on a wall or ceiling, you're looking at one or more remote APs. If you don't want to reuse your current router as an AP (and depending on where the stability problems you spoke of lie, you may not), then the Ubiquiti hardware is wonderful. Start with a single AP and add more if needed, simply by plugging them in and adopting them. And they're definitely more aesthetically pleasing. They're no more intrusive than a smoke detector. You can even disable the LED lighting in software.
TL;DR: Even if AC hardware was well-supported in FreeBSD, you're nearly always better off with external APs, mostly for ease of placement.

this board only has one PWM/DC fan header so you have to do this trick. you can play around with it but this is how I did it. i used a noctua pwm extension cable I had and connected it to the only mobo fan header. Then I connected a y splitter to the other end. That gave me two male PWM connections. Then I connected two more PWM Y splitters to each end of the first PWM Y splitter. that gives me 4 PWM fan headers for my case. I happen to have 4x 120mm fans.
Keep in mind, that 1 PWM/DC header on a motherboard only can provide a maximum of 0,5A,
So in practice, more then 3 fans at 1 header is not recommended.
That's why molex to Fan connectors are made, that way you can go far beyond the 0,5A and go untill the 5V powerline of your PSU max out.
Also, by adding more then 1 fan to a PWM/DC header on your motherboard,
you are heating up your motherboard, because it draws much more power through it for feeding all those fans.Grtz
DeLoreanI agree 100%. However in this case, I double checked the manual before I did it. It says:
"The Chassis Optional/Water Pump Fan supports the water cooler fan of maximum 1.5A (18W) fan power."
Because I was looking at this mobo (after I bought it) and couldn't understand the one fan header concept on a 2017 board. Then when I was digging through my extra computer fan components, I noticed on a noctua box I had, it actually recommended chaining y-splitters to be able to keep fan speeds in sync with each other. Being I come from a time before adequately powered fan headers, I was blown away by the concept. It certainly makes more sense doing it this way when you think about it. barring speciality need situations
So I did 4 splits. Just an example, each fan 12v*0.1a = 1.2watts
4x0.1a = 0.4amp.
4x1.2w = 4.8watts.Got some spare room there for what I did.
Now it's starting to make sense why mobo's have specially labeled water pump fan headers, more power on that header to aggregate the radiator fans and the pump all powered from one mobo header.

Definitely about wifi on pfsense like the plague, especially since you already own a solid router. Just use it as an AP. Is also recommend avoiding DDWRT, OpenWRT, Tomato, etc. Those are excellent when trying to do more work a SOHO router, but when using it only as an AP they are often actually slower than stock firmware. About the only reason I could think of to switch to one of those is if your stock firmware doesn't support VLANs.
I like the Synology router because it can go into "Ap" mode with just setting click. But it also removes all the cool features like analytics. havent yet found a decently priced AP. the only stock firmware I like is synology. every other vendor has a web ui that looks like it was made in china for $100

Hi all,
New here, but an IT systems admin that has finally had enough of trying to run his home network (borderlining on enterprise-grade home network) through an Asus AC3200 router. The ASUS is a great router, but it can't keep up with the amount of traffic I'm pushing through it consistently (2 plex servers, 40+ wired devices, constant IO 24/7)… I have to reboot it almost daily and even then it could perform better.
It's finally time to build a machine that can handle my firewalling appropriatly, and keep up with the traffic I'm trying to send through it. I've been researching and researching across these forms for days, and here's what I have come up with:
+Motherboard: ASRock H270M-ITX/ac LGA 1151 Intel H270
– My thought here is it has two onboard Intel NICs, the 1219V (apparently one of the best Intel desktop-grade NICs?), and the 1211, and it has onboard AC. I have heard Wifi is... sketchy... on pfSense? Or at least, it takes more processing power.......
+Thermaltake Core V1 Mini ITX Cube Case
–It's a little bigger than is probably necessary, but I have the space for it, and it looks nice... and it's cheap.Thoughts and/or advice on this would be great. I don't KNOW what resource-heavy processes I might need, but I'd rather have a system that can perform flawlessly with the high amount of traffic I'm pushing through it, even if I spend a little more and only use 10-30% of the CPU most of the time. That way if I NEED it, and all of a sudden have to have all my devices pulling data through at the same time, I want it to be able to handle it. I'm fairly sure that's the bottleneck on my asus, is that it's a 1.7Ghz dual core processor, and I'm just pushing a Ton through it.
Outside of this, my whole network is connected by gigabit (Cat6/Cat7) and 5 or 8 port Netgear ProSafe Plus GS108E managed switches... everything is there for peak performance... I just need the device that can run it all with the most uptime, performance, and stability as possible. Do you guys think this will do the trick? Or is this still way overkill....?
I'm about to build a machine to run pfsense. I chose the same motherboard and case with 8GB RAM, but I went with a Core i3-7100 CPU. I'm re-purposing a 120GB Samsung 840 SSD. I'd have all the parts right now, but Fedex delivered them to the wrong address this morning! >:( Looking forward to getting started on this project. I too have 1 gig fiber u/d, and my house is wired with CAT6. ;D

Hi guys,
I have the same MB model and i want to install pfsense on it. For the ones that have it, can you tell me if the built wifi card is recognized by pfsense? I know it is easier and better to have an external AP, but i just want to know the compatibility feature before i install it.
And also, does pfsense recognize both NICs?Thanks.

anyone?

Hard to say exactly what that wifi chip is beyond Intel and supports 802.11AC.
However just based on that I can say it may not be supported at all.
If it is supported it will only run in 802.11N mode at most and it will not run in hostap mode. You could not run it as an access point.Steve

Thank you for reply.
Probable the wifi card model is this one
I found this on another forum.
But why do you say it won't work as a hostap? Is there a chart somewhere, or how do you have this certitude? -
That card is at least supported, by the iwm(4) driver.
However as it says there it supports station mode (client) only.
As far as I know no Intel cards support hostap mode, in FreeBSD at least.It will also connect only at 802.11N because there is no AC support in FreeBSD.

ASUS router: It sounds like you need to support a lot of simultaneous connections, so just about anything you build is going to be better than this cheap toy.
Mobo: Nice dual Intel NICs. pfSense doesn't support AC wifi yet, so the wireless probably won't work. If it isn't Atheros, it's probably never going to work. You should also check that it can run as an AP if you want to use, but you're probably better off using the ASUS as an AP. That's about the only thing it's good for.
CPU: Maybe overkill. I would build with a power efficient chip rather than a powerful one.
RAM: Probably overkill unless you are getting a great deal, and you are going to use ZFS and snort.
Samsung NVMe: Pointless. pfSense only needs IO when it is updating, which is pretty rare. I use USB drives in my build for the cost and power use advantages.
Intel NIC: Good card. It's probably what I would use if the onboard NICs don't deliver.
Case: Cheap is good. It doesn't need to do anything but be a box.
It's a very powerful build that leaves you a lot of room to grow, but you are paying for it with the additional electricity costs. Also, you are reaching the price point where the more compact and power efficient SG-3100 is a competitive option.

@signalz and @stephenw10
Thanks both for you answers. It appears i have no chance using the wifi card onboard, as an host AP. I will move on then...
Regarding the setup, it is a bit overkill , yes. I have a 35W i3 CPU and 8GB RAM with a normal HDD. I read about the inutility of having a SSD in this case. THe power supply has 250W and it is the smallest one i could find to fit in a 1U case.
Thank you again guys.
