You could be right, it might just be unintentional blocking. I would certainly prefer this version vs intentional blocking since the later is pretty much security by obscurity (as long as you don't know the code you can't do harm...)

But if the LAN authorities think, as he did, that 192.0.0.0/8 is all private, instead of just 192.168.0.0/16, then their routing tables may be set up to not forward 192.30.252.141 to the outside world, but route the entire 192.0.0.0/8 to the inside only. Which would time out.
