Passive Port Range (for FTP connections): The default range is 3000-3100, the same as the MOVEit Transfer default. The Passive Port Range does not need to be the same as MOVEit Transfer's but it's probably best for consistency. The number of ports allowed should not exceed the number allowed by MOVEit Transfer. Note: A passive port range limits the number of concurrent transfers.
Note: You may be warned that any running FTP proxies will be restarted when changing the port range.
