Young Sent: Thursday, September 28, 2006 11:52 AM To: isapros@xxxxxxxxxxxxx Subject: [isapros] Re: It's the FTP filter Hmmm. might it be because the FTP filter is trying to look into the encrypted traffic? Are you trying to SSL out or in? If in, you may need to set up a FTPSSL listener like an HTTPS listener? Have you tried playing with SFTP, which is essentially FTP over SSH (tcp 22)?

If I disable the FTP filter in ISA, then I can connect to the site. However, I can't connect to any "normal" FTP site while that filter is disabled. Amy
