This enables you to have several machines on a local net accessing the outside through one iface. The internal IP's are not visible from the outside. It does not let external machines distinguish your internal boxes though. E.g. you cannot ftp from the outside to your internal machines, only to your 'tun0-box'. There is nothing wrong in letting your 'tun0-box' also handle mail and have a http-server. Well, apart from some security issues. Many sites will have the http-server as a standalone box with everything firewalled except port 80. And let mail be handled by yet another firewalled box etc. But that's going a bit far into the subject... [Droning on] Unless you are paranoid or are very intrusion prone I would not bother with the firewalling stuff.
