My users can sent small test files to Robo-FTP Server, but when they sent the larger data files, the connection drops. Why?
Check the MTU on your firewall. If the MTU is too small, the firewall will only allow small files through.
MTU stands for Maximum Transmission Unit. This setting limits the maximum packet size that the Firewall will allow through. A test file which only contains the line "test file; please ignore" (for example) could be sent as a single data packet with a size under the MTU.
However, a larger file would have to be divided into several large packets. If the packet size exceeds the MTU, then the firewall will block the transfer.
