I have a firepower 1010 managed with FDM and have been trying to expose my ftp server to the web and cant get it out there for nothing.
I have allowed access from the ftp server to the outside interface on port 21 and vice versa.
Then i setup NAT to translate the ftp server to the outside interface and vice versa but no luck.
Its a freeNAS server with the FTP service on and its works fine internally.
I also have my ISP fiber modem in passthru mode.
What could I be missing here? (Screenshots attached for reference)
