Ok, I did that. Hmmmm, interesting....

nslookup www.google.com

Definitely makes a difference for some (most?) web pages, but not all. 
cnn.com for instance took minutes to load, and spewed out hundreds of 
dns lines in my ethereal trace.

lynx www.google.com

Removing that default route certainly has an effect - but it doesn't 
seem to be a consistent one. Does that output help?

(really appreciate you (daniel) and whoever else actually takes the time 
to look at this!)

Thanks,
