Expert Mode: FTP, Firewall/Router Settings

 

·Passive: If the FTP server is behind a firewall then you may need to enable this option. If SyncBackSE can login to the FTP server, but cannot transfer files or retrieve a folder listing, then try enabling this option to see if it fixes the problem.

 

·Use Clear Command Channel (CCC): Choose this option if you are behind a firewall or router that uses NAT (Network Address Translation) and you are having connection problems. Some routers can dynamically change the FTP communication to translate I.P. addresses but this can only be done if that part of the FTP communication is not encrypted.

 

·External I. P. address: If you are behind a router, and are using NAT (Network Address Translation), then you may need to enter your external I.P. address here. This is usually the I.P. address of your router and is not a local I.P. address. This option is not required (or enabled) when using passive connections.

 

·Use ports ranging from...: If you are behind a firewall then this is the range of TCP ports that you must open on your firewall to allow the FTP server to contact SyncBackSE. If the ports are not open then files cannot be transferred. This option is not required (or enabled) when using passive connections.
