Nice, although it doesn't explain the purpose of having the routes if you

internal network from surfing the bogon web which can't reply back anyways?

  It's a generic config -- note the "! Default route to the Internet 
[...]".  Saves you some microbucks on that burstable Internet link, 
or maybe some of that micro-upstream-bandwidth on your ADSL when you 
get those spoofy pings.  Hey -- you asked.  I recommend it myself, on 
a smaller scale.
  (Sigh.)  Your ideas are nice, but I'd have to rant all over this 
list to keep y'all from filtering my compelling bogon content.
