FTP issues using filezilla

Yes Brad, Session is timing out and I have tried allowing data-port 20 and 0. Both gave me same results. virtual config ltm virtual vs_test01_ { auto-lasthop enabled destination x.x.x.2:ftp ip-protocol tcp mask 255.255.255.255 partition Corp_Non-prod pool pl_test01 profiles { /Common/tcp { } ftp_test { } } source 0.0.0.0/0 source-address-translation { type automap } vs-index 92 } Thanks, Sekhar

What is timing out exactly? The opening of the control channel? The opening of the data channel? or is it timing out while a file is being transferred?

after initializing tls command on filezilla client time outs intially it retries again and fails.. this is the output on zilla client Status:Connecting to x.x.x.2:21... Status:Connection established, waiting for welcome message... Status:Initializing TLS... Error:Connection timed out after 20 seconds of inactivity Error:Could not connect to server Status:Waiting to retry... Status:Connecting to x.x.x.2:21... Status:Connection established, waiting for welcome message... Response:220-Welcome to FTP! Response:220 CrushFTP Server Ready! Command:AUTH TLS Response:234 Changing to secure mode... Status:Initializing TLS... Error:Connection timed out after 20 seconds of inactivity Error:Could not connect to server Status:Disconnected from server Thanks, Sekhar

Sounds like you are using FTPS which adds SSL onto FTP. I don't believe the current FTP profile supports SSL offload of FTPS. You have two options to consider. Check out these resources. They should get you to where you need to be. https://support.f5.com/kb/en-us/solutions/public/9000/300/sol9347.html https://devcentral.f5.com/articles/ftps-offload-via-irules
