I'm having troubles connecting to ftps via Filezilla. They told me it could be router ports. Some say 21 port (exit traffic?) is always open, some say it's closed. How do I check if it's open? If it's closed, how do I open it? Could it be something else? The ftp server works perfectly since I've asked my friends to connect and they succeed at it.The router is a d6000.
Edit: I'm running on w7. Indeed, I need my computer to read and upload content from an ftp. FileZilla connects to server but waits forever when tries to read directory list. I tried passive and active mode but none works. I'm confused, do I need inbound traffic for it through port 21 or not? I can connect from another pc and another router with the same software settings, that's why I'm asking about the router.
