Using 4.4(7) code on a pix 515, default fixup statement for ftp, and both NAT and PAT configured. FTP requests for large files hang after a seemingly random amount of time. I reviewed the field notice regarding PTR records in the DNS, but I don't think that this applies in our case. Is there any known fix for this issue?
