Dear Tom, I've successfully deploy ISA Server based on your Book "CONFIGURING ISA SERVER 2000" but one thing about publishing FTP server behing the ISA machine. Since I published my internal webserver and port 21 is included in the wizard, I can't do a server publishing for ftp since the port already there. So, how do I? Because your book does not explicitly tell me how to publish an independent ftp server behind the ISA machine? Or..do I miss something about this? Thanks & Regards, Gunawan
