Problem with an FTP server

Asked By 0 points N/A Posted on -


I have a problem with an FTP server I'm trying to run on my PC.
I have installed xlight FTP and I have set it up so that it gets a dynamic IP from my router. On my router I have opened port 21 and I have configured it so that it port forwards to my PC's IP. I have disabled the security service from my ISP. Also I have configured my firewall properly.

When I connect to my FTP server from a local host, everything works great. But I can't connect from a host outside my LAN (through the Internet). Any ideas what may cause this?

Problem with an FTP server



There are bunch of solutions , you should try them all one by one 🙂 .

I hope one of them will solve your issue.

1. Check your Firewall settings, make an exception for xlight FTP server program.


2. Try to Telnet your FTP server from outside the LAN, if you are unable to Telnet it, then at least you will know the cause i.e. Whether it's a software problem or what.


3. Change the port number of your FTP server, by default its 21, make it something else. Because many ISP's block port no. 21 so as to prevent FTP servers.


4. Use FTP client like Xlight FTP client rather than accessing an FTP server through a browser.
