We're having trouble getting to our FTP server from behind a Cisco ASA firewall that we just installed. We've got HTTP and other protocols working, but FTP doesn't seem to work properly.
I can connect to the server, but I can't do any commands in it. Which I think has something to do with passive and active FTP modes.
Is there an issue regarding a negotiated port that I'll never really know until after the server has connected?
