OS choice for home router/firewall on old hardware?

Question

Computer networks

stonegate fw-315 lies, gathers dust Intel atom 2core 1.8GHz 2Gb 4intellGbEthernet
I would like a clear, convenient configuration of the network stack and a full-fledged shell and driving pleasure.
A piece of iron is a bust for home routing, I want to use its resource to support services (well, there is a torrent rocker, a media center)
I'm more of a developer than a network administrator, I can write and compile services for it myself, so I want an easy route setup and a full-fledged OS at the same time.
While the leaders of the OpenBSD and Vyos shortlist, maybe experienced networkers will advise, share their experience (PacketFilter vs NetFilter / IPtables / Quagga and all that)
I would be grateful.

Answer 1

FreeBSD is well suited for such purposes. PF, and a good networking stack... And less hardcore than OpenBSD. =)
But if Linux is more familiar, then Vyos is also possible.
Or even any server Linux, and set up the firewall and routing yourself, especially since for home purposes it is not difficult, and the skill will be pumped. =) And get, as a bonus, a really full-fledged environment, and the ability to install arbitrary software without problems.
But in the end, most likely, the problem will be the ability to download at least something from this, on the specified piece of iron, in view of its specifics. =)

Answer 2

You get from chefs asking which knife is better)))
You need the Axis that you know, or the one about which you can not only find information on setting, but also understand it.
Spend some time on this, the rules of firewall, routing can be called the same, the syntax and applications on the axes are different, but the logic of all this stuff is the same.

If you are bored and want to study something, poke - RouterOS on the command line. If simply done, then *BSD
