However, NAT and filtering add a fair amount of CPU-bound latency. At one
time, my gateway was an Ultra 1e m170, and the combination of NAT +
filtering + PPPoE made performance absolutely awful.
I then moved the PPPoE onto a separate box, and performance was tolerable.
However, anything with a large number of connections across the gateway
(e.g. bittorrent) would make the entire connection unusable.
Moving the whole stack onto a modern mini-ITX (VIA C7) system was a
tremendous improvement in both performance and watts consumed. It was the
first PC-based bit of infrastructure on my network, and that made me a
little sad, but the power consumed by two pizza-box SPARCs just to get me
a rubbish network connection was sadder still.
All systems involved were running OpenBSD with pf, named, and nearly
nothing else. My connection to the outside is nominally 8Mb/s down and
