Connection to FTP times out [SOLVED]

neuwerld · 2009-06-04 11:51:23

Hello!
I would like to have some help with my work on setting up an FTP server at my home.
First of i'm using Proftpd on the ftp server and I have made a DNS name for my external IP on dyndns.com.
It works fine when im connecting with the local IP from a computer on the network but when I try to connect to
ftp://neuwerld.mine.nu it just times out?

I don´t understand what is wrong, I will give my proftpd config and you can see if there is something strange.

#
# /etc/proftpd/proftpd.conf -- This is a basic ProFTPD configuration file.
# To really apply changes reload proftpd after modifications.

I have opened the port 21 in my router but I dont know if there is some more port that has to be opened?
When I try to connect to the FTP I have tried IE and Filezilla.
Doesnt I have to forward somewhere else so the connectin computer knows that it is the server in the network that is the FTP and not any other of the computers.

EDIT!

This is the output of Filezilla when trying to connect.

I think the problem here may be the NAT router. You might have to forward the range of ports specified as "PassivePorts" in the config file to the FTP server.

This may help: http://slacksite.com/other/ftp.html

Thanks man!

I got it working by uncommenting the PassivePorts and open them in the router.
