jftpgw is an FTP proxy/gateway that uses the FTP protocol (unlike those FTP proxies that fetch an FTP file but work as an HTTP proxy). You can use it to make servers behind a firewall/NAT server (masquerading server) accessible or to allow users behind such solutions to transfer files to and from the outside of the LAN.WWW: http://www.mcknight.de/jftpgw/
