抽取MongoDB，如何设置不探测mongodb实例的真实地址

因为网络问题，连接mongodb数据库需要通过固定ip来连接。但是datax同步时，绕过了固定ip,连接的是真是数据库地址，导致网络不通出现同步失败；各位i大佬这块是怎么解决的？？？

No file, test, or entry point is named; start by locating DataX's MongoDB extraction implementation and tracing how the configured fixed IP is used during connection setup. Reproduce the case with a fixed IP whose MongoDB advertises a different address, and consider the work complete when extraction does not switch to the advertised address and succeeds through the configured endpoint.
