OpenBSD as I have happily been doing for years with my old Sparcs.

doing nothing... Its too noisy though for running 24/7, so I

I used a SPARC Classic as
my home firewall for over 10 years. Worked quite well! And yes, the on-board
interface is 'le'.
I never had a qfe in mine, but did have a 'qe' card (4
10Mbps ports). This worked great in the Classic, though I think Solaris
dropped support for it after Solaris 7. I think you could still use the 'qe'
driver from Sol. 7 however, which is how I was able to run Sol. 8 on my
I think there's a chance a qfe would work in the Classic. Though
it would be so slow there's likely no point. I remember Sun giving sizing
advice in '95 or so, when the UltraSPARCs were new, that you should have
100Mhz of CPU per 100Mbps port. So clearly that math doesn't work on the
A good, cheap (but non-Sun) firewall would be a small PC with 2
available PCI slots. Drop in a couple of old Intel PRO/1000 dual-port GigE
cards (can be had on eBay for under $20 IIRC). They won't run full speed
either, but you will be able to do 100Mbps+. Then run pfSense on the box, off
of a USB stick or small ATA flash module of some sort. Should be very nice.
