I'm willing to bet it's the DSL modem and that the actual buffer size  
is a binary-round number, likely 64kB.

The NAT box isn't naturally a bottleneck and the brand you have  
doesn't attempt to impose an artificial one.

By the way, buffer provisioning for slow links is a problem that's  
harder than the "one RTT worth divided by whatnot" rule makes it out  
to be.  If anyone who makes DSL/cable modems is listening, please  
don't just cut the buffer -- it may well do more harm than good.
