So... This is not a real Web Filter question, but as the forum is structured like the WebAdmin categories I thought I could as well post it here.
How can I prevent the FTP proxy (non-transparent mode) from being used anonymously? Right now, everyone can connect to any FTP Server anonymously by using :2121 as a proxy. However, I want the users to have to authenticate first.
To be clear, how do I enforce mandatory authentication for the non-transparent FTP proxy using port 2121 like it's possible with the web filter?
