Very good to know this, though it doesn't direct all other input to the remote machine. Using windowskey+E for example is performed locally. +1 anyway.

Could you explain how NAT Hairpinning differs from NAT Loopback? Thanks!

comment Random 'Drivers installed message' appeared and lost internet connection suddenly
This is a hardware or software issue, not a security issue. It might be, but a lamp going dark can also be a security issue while it probably just burned out. Your network hardware got reconnected, which is probably a bug in the driver or something, and the cause is not related to security.

comment Why does pinging 192.168.072 (only 2 dots) return a response from 192.168.0.58?
Try loading 1249739915. In Chrome it translates to 74.125.132.139, in Firefox it loads that URL. Related: php.net/ip2long

comment TCP/UDP hole punching from and to the same NAT network
@DavidSchwartz It doesn't have to rewrite both fields. It seems (also seeing the answer that was just posted) my question is a bit unclear...

comment TCP/UDP hole punching from and to the same NAT network
The block is probably to mitigate attacks such as ARP cache poisoning or browsing SMB shares or so. Hole punching enables a direct connection while still making these attacks impossible (also basically, the traffic is identical to internet traffic). Legal issues aside though, the point is that internal IPs aren't usable because internal traffic between hosts is blocked. When the udp/tcp hole is made, the public IP from the clients will be used. I was wondering how the NAT router reacted to a packet that both comes from and goes to his WAN IP, especially when it hasn't got NAT loopback.

@mpajoh At the notepadplusplus.org website there are links to Google+, Twitter and Facebook on every page. And also: notepad-plus-plus.org/contributors/author.html sourceforge.net/projects/notepad-plus/forums This should be enough to get in touch.
