I just updated to PIX v7.22 code. FTP worked great before. After
update, FTP is broken on all Internet Explorer 7 clients and only
works intermittently on Internet Explorer v6.0. I have about 20 end-
users who rely on FTP. I do not do Anonymous FTP. Part of my research
led to a port speed/duplex mismatch, so I checked my HP 2524 and PIX
515. Indeed, there was a mismatch, so I corrected it. Here is my PIX
config. Thanks in advance for the help.
