RE: FTPS firewall compatibility

Thanks, how did you get it to use 991? I do have 990/989 opened through the FW, but I am not selecting 989, it's the active FTP transfer port that my iSeries is using by default. What is weird is I can see 989 open on the server system in NETSTAT, but it just sits there are never transfers data. I think the FW has logic that blows this up because it cannot "see" the packets.

Once you connect have you tried to go into passive mode. SEND PASV? I see you are using active mode but has your firewall admin opened up 989 and it that open at the remote end? We here use 990/991 combo.

All,

I cannot get FTPS to work on our firewalled iSeries systems. We are using active mode FTP, with and without clear command channel. The control port does function (990), but anything that sends or retrieves data over the transfer port (989) just stalls. I know it has something to do with the FW not being able to see information in the encrypted packets, but "ccc" clear command channel is supposed to remedy that right? SFTP would work because everything goes over the secure shell port, but our application uses the native iSeries FTP. So I am stuck trying to use FTPS only. Anyway, I am tired of unsuccessful trial and error. Does anyone out there have advice on this subject? Surely I cannot be the only guy using iSeries behind a FW.
