Actually, now that I dig in, it only seems to be routing dns traffic.

That is, I tried to ping the wireless interface from my daughter's computer
and got a network not reachable or down result of some sort. (I didn't
write the exact message down, and my daughter's at school so I can't
use her computer.)

But my logs on the netbook that is running hostapd and dnsmasq show
quite a bit of dns traffic, lots of queries returning successful results.

No problem there.

That also got network not reachable or down or something.

I tried that in bridge configuration just now and I'm only getting one
percent every twenty to thirty seconds. The non-bridged configuration
doesn't even read the mail to look at the url.

One of these days I'll get someone to pay me
to design a language that combines the best of Forth and C.
Then I'll be able to leap wide instruction sets with a single #ifdef,
run faster than a speeding infinite loop with a #define,
and stop all integer size bugs with my bare cast.
