Network Configuration

Setting up network components for FTP is not trivial for use outside your LAN (Local Area Network). Since so many firewalls and routers exist, it is impractical to give detailed step-by-step instructions suitable for every user. It is important to understand the basics of the FTP protocol in order to configure FileZilla and the routers and/or firewalls involved. This documentation describes the history of the FTP protocol and how some aspects of the protocol work. Reading it carefully will save you a lot of trouble setting up FTP.
