Hi Dieter. Yes, we have tried both passive and non passive FTP. In either case, according to the Z2.log we get enter Zope successfully, but the session appears to hang on the FTP "LIST" command. No files or directories are visible.

Several folks have pointed to NAT problems, but why this problem would only show up only at the "LIST" request does not make sense to me.

because "LIST" is handeld by FTP data connection. passive FTP goes like this: 1) FTP-Client Port >= 1024 ==== contol connection;SYN ====> FTP-Server Port 21 2) FTP-Client Port >= 1024 <=== contol connection ===== FTP-Server Port 21 3) FTP-Client Port >= 1024 ==== contol connection PASV ====> FTP-Server Port 21 4) FTP-Client Port >= 1024 <=== contol connection OK 4546 ===== FTP-Server Port 21 5) FTP-Client Port >= 1024 ==== data connection SYN ====> FTP-Server Port 4546 6) FTP-Client Port >= 1024 <=== data connecton ===== FTP-Server Port 4546 I would check my NAT rules (high ports >= 1024). There must be something wrong with data connection on high ports. Hope you'll find it. Bye Marcus
