I am trying to re-mage an SFR module on an ASA but when I do a system install via ftp, I get a permission denied error. I have ruled out the FTP server as the issue as I am able to FTP to a totally different set of firewalls so that should rule out the server as the issue. I then connected locally to the inside interface of the asa (basically just putting my laptop in the same subnet/vlan) as the inside interface and get the same error. I also tried to source from different interfaces (inside, management) with no luck. I have never seen this before where you can't ftp. NOTE: TFTP does work to the asa but from all I have read when you do the system install on the SFR you cannot use TFTP.
