Considering to purchase Secure SDK Pro.

WS_FTP Pro client is able to do data transfers to needed server from behind firewall only when it knows external IP with "SSL Force PORT IP" option. Otherwise it sends internal IP in PORT command.

Anyone knows if this option is awailable in SDK as well?

Reviewing programming interface reference from WS_FTP Pro SDK User's Guide I couldnt such option.

Thanks,

No, in the current version it is not possible to define the external IP address.   However, a new version that is about to be released has this feature.

I simply added a ORT# to the tail end of the ftp:// connection string
