I am looking for a software based firewall for my edge gateway, I was originally planning to just use pfsense, but I saw the fuller feature set that Sophos offers for free with the home edition. This seems like a pretty good bargain but the big gotcha is 4 cores 6gb ram limitation.
The hardware that I already have in place is an intel 10th gen itx build. I haven't bought the processor yet, but I am leaning towards an i3-10320 being as it has the highest base and turbo clocks for a 4 core. Alternatively I could get a 10600k with a 4.1GHz base clock, so the 4 cores that the home edition uses will at least be fast enough.
I have 1gig fiber internet and that is the minimum throughput (preferably IPS throughput) that I'm trying to achieve. But the hardware will have an intel 4 port SFP+ card with at least 2 ports actually needing 10gig. I am still unsure if the cpu limitations will affect this desired throughput? Also, is 6gb enough to be running most of the offerred security features?
There wont be a ton of traffic volume going through, but a couple users at a time transferring large files / remote desktop activities necessitate more than 1gig of internal bandwidth. Coupled with normal internet traffic and some vpn activity, I hope I can strive for this goal with the home edition restrictions.
Is this possible? Or should I look elsewhere for a more powerfull software firewall?
