FTP Proxy
A proxy configured specifically for File Transfer Protocol connections.
An FTP proxy is a proxy server configured specifically to relay File Transfer Protocol connections, mediating between an FTP client and the destination server. It handles FTP's quirks — separate control and data channels, active versus passive modes — that generic HTTP proxies don't manage, and appears as a distinct field in OS and network proxy settings.
Media buyers touch this rarely: the main context is uploading landers and creatives to hosting via FTP while wanting the upload to originate from an operational IP rather than a personal one, or working through infrastructure where all traffic must pass a proxy. In modern stacks, SOCKS5 handles FTP traffic fine, so a dedicated FTP proxy is mostly a legacy checkbox — just don't confuse the settings fields when configuring a machine.
In buyer speech
“Push the lander files through the FTP proxy on the ops box, not from your home connection — keep the hosting footprint clean.”
