FTP access timeout behnid isa 2004

[vbussiro]

Hi,

I've got a problem accessing ftp sites. I'm behind an isa 2004, and made rules allowing ftp protocol (disabled/enabled ftp filter, disabled read only ftp, installed isa firewall client, no changes).

I can access root of the ftp site, but when i try to list a folder, i get a timeout.

Any idea ?
