To the OP: Be aware that depending on the local laws you might (will) be
responsible if the NATed IP is used in criminal affairs (downloads,
child porno, etc.); at least the local authorities will ask you who used
that IP and take your complete system with them for further
investigations, scanning your logs and disks;
even if it is a nice idea and you have good neighbors, I would not do
that here in Germany;
