I have set up a FTP server, DDNS, the network can be accessed through fileZilla and client software, you can also use imacbook outside network access (browser, visit, including normal, speed is very fast), you can also use Windows laptop inside of Chrome normal visit, build folder various operations also normal, but is unable to IE above or my computer access inside, is there a master can help me with, very confused, by the way, forget that the inside of the IE FTP passive mode has been cancelled,

Thank you very much!
