We have a web server on our DMZ via PIX DMZ. We also have an internal web server that has some of our documentation files that is on our internal side of the PIX. We update the internal files on our internal web server, and we would like to be able to have the folder structure/ file structure available on our DMZ web server. What would be the best way to transfer files between our internal web server to the DMZ web server across the PIX firewall to be the most secure way of transfering files without opening up any security vulnerabilities in our network. I need some ideas on how to transfer these files (either by file copy, or FTP) and how should I configure my PIX to keep everything as secure as possible, and still allow the files to be transferred.
