are perfect for such a role, with a second ethernet port on an SBUS card. It's a
rather light-duty Sparc, but by running on a fairly foreign architecture instead of a
common Intel box I'll miss out on all but the most determined crackers.
Any suggestions of a better battery (cheaper, mostly) to 'strap on' to Sun NVRAMs?
I am going to use AAA lithiums on this machine, which should last forever, but
they're a bit pricey.

I wonder if you even need a P200 for that. I used to manage a
networks that had a 486dx/66 doing all but SpamaAssassin. For the rate it
had to handle on the DSL port (actually fractional T1 256kb/S) it never
seemed to be working hard. The PS in it was only 200W and nowhere was
it ever stressed. It's claim to fame was running at room temp over a
weekend in the summer with both PS and CPU fan siezed without melting
or even getting upset.
Also an older 500mb-1gb drive will use less power than a newer fast
spinning drive. Or better yet netboot it and only keep a floppy. Pull
all the IO you don't need and run the video at 640x480x256 as a further
power reduction. Use a monitor (or KVM switch) as you don't need
a monitor save to check on it.
