OK, can anyone advice what would be better to get TOPTON i7-1165G7 i211AT 6LAN or QOTOM Q575G6 i7-7500U i211AT 6LAN. I'm on PPPoE FTTP (UK). With current electricity prices I'm trying to find most efficent solution(without breaking the bank [ie. SG-6100 max]).
@akuma1x Yes it's easy enough to buy some secondhand/commodity hardware.
Anything you can find with enough network ports and an Atom C3XXX, or Intel i3/i5/i7 processors, or even some of the more recent fast Celeron and Xeon processors. Those are all good for a pfsense box. Try to stay away from the laptop-grade mobile processors, and the older Celeron J1900 stuff. Those are going to show their age and weaknesses quicker than the other ones.
HP and Dell made/make some good small form factor stuff. Just make sure you can add at least 1 multi-port INTEL network card in there and you'll be all set with a nice pfsense firewall box.
and more specific, this one's an i5 https://www.amazon.com/QOTOM-Q355G4-Factory-Firewall-Multi-Function-Appliance/dp/B06XNWLR3J/ref=sr_1_fkmr2_2?keywords=pfsense+firewall+black-boxes+i5&qid=1553882807&s=gateway&sr=8-2-fkmr2
This one is a much better choice!
I'm going to get up on my soap box here... keep in mind, you should try to support the pfsense open source project as much as you can. With the Qotom box you found, you're only about $60 away from the "official" Netgate SG-3100 box. I'm not trying to guilt you into a purchase, and I'm not saying you're going to get a better experience with name-brand or not, but being that close in price, I would send my money to Netgate and the firewall project itself.
At first his ISP thought he was going over his rated speed, but we traffic shaped and determined that was not the problem. His ISP now thinks it is the PPPoE Keep Alives not being recieved thus terminating his line. How would he got about mitigating this on the SG-1000?
