Note: Most communication vendor's supplied boxes are shipped with that block already installed, since these are among the most popular attack vectors.

Note2: The client (Kindle) is already firewalled against these ports in-bound.

Good advice. But if anyone actually FINDS a netty box that allows those connections in by default? It's time to line up against the wall... Bang!

Seriously check it out. It was a popular pastime trawling huge (advertised if you know where to look) Greenfield IP ranges with toys like.. hmm let me think "Nessus" and one with a name to do with lines or rays or something.

Anyway, it's a good idea to know your router is secure.
whether you have a Kindle or not.
