Hi I have a question not strectly closely related to squid but I hope that someone kindly will reply to me. I saw questions about ftp reverse proxy, reverse proxy etc... But what exactly is an ftp reverse proxy? What is the difference at tcp layer? Example: Internet | | Firewall----dmz | ftp server (private ip) | Lan Usually I configure a static nat (public ip to dmz ip) in order to provide ftp service but if I would to configure a reverse proxy with squid is possible? My final config should be like this: Internet | | Firewall----dmz | squid (reverse ftp) | Lan Internal Ftp server To sum up squid should forward incoming ftp request to my internal ftp server The question is: 1) Is Squid able to act as reverse ftp proxy? 2) What is the difference at tcp layer? Thanks Marco
