How do I change my FTP port from 21 to 8888?
On the local network the FTP-server works fine with port 8888. But it can not be accessed from the internet. The FTP client logs on, byt cannot list the files. Gets the error: Transfer channel can't be opened
I think I need to redirect some extra port since I am not using port 21.
What is wrong?
There is my conf om my ASA5500
