OK.  I'm finally at home again (I've been traveling for work) and got a 
chance to play around to test it.  It turns out it wasn't my router 
configuration, it was my browser configuration.

The payment site is verifying the Referer header and my browser was not 
sending that header.  The off-network computer I tried was configured to 
send the Referer, so it worked on that one.  I could have sworn I had 
tested that when I was trying to buy initially (as many websites are 
broken^H^H^H^H^H^Hconfigured to require a specific Referer value, so I 
usually remember to check).

/me wonders if he should mention the futility of using /any/ 
client-side-generated data for "security" purposes...  I guess, though, 
that's not Openmoko's problem, but Hi Trust's.
