Although site-to-site transfers (FXP command) can expedite what otherwise could be a slow transfer, many administrators consider site-to-site transfers a security risk, exposing servers to "port theft" or "FTP by proxy" attacks. Depending on how your servers are configured, you might want to block these types of transfers.
To allow or not allow Site-to-Site transfers
In the Administrator, connect to EFT Server and click the Server tab.
In the left pane, click the Settings Template or user account that you want to configure.
In the right pane, click the Connections tab.
Click FTP Config. The FTP Settings dialog box appears.
Do one of the following:
To allow transfers, select the Allow site-to-site transfers (FXP) check box.
To block transfers, clear the Allow site-to-site transfers (FXP) check box.
Click OK to close the FTP Settings dialog box.
Click Apply to save the changes on EFT Server.
