It's not just an issue with the Linksys though.  I was also caught out by 
this.  Since I don't have a Linksys, there were no problems at my end, but 
I had plenty of trouble contecting to various websites (try clicking the 
download link for JAF from Sun at 
http://java.sun.com/products/javabeans/glasgow/jaf.html or connection to 
IBM's Rational Rose site at http://www.rational.com/ ).  These aren't 
small time operators either.

And it's not obvious what the problem was - I could believe that one site 
was down, by after several, I started to wonder and investigate.  If this 
is on by default in FC2, there could be plenty of unhappy bunnies with no 
idea why they can't access certain sites.
