How to setup a router (nat) for running a ftp server (RaidenFTPD)

A : Running a ftp server behind a router (NAT) had always been hard, almost nobody can success without necessary knowledge and manual configuration on routers and ftp server softwares, you usually need to apply for a dynamic IP domain name, configure your router manually for port mapping setup, configure your ftp server manually because it is behind a NAT so it does not know your real Internet IP-Address for passive connections to use.

Now things had changed , with latest RaidenFTPD v2.4 build 3436+ with UPnP NAT traversal, all the above troubles are all gone, the RaidenFTPD UPnP NAT traversal can do the following things for you automatically

* configure necessary port mapping setup on your router (Internet gateway device) automatically
