I'm setting up a proftpd 1.2.6 to a slack 8.1 server. This is my friends server.
The server runs well, but there is one problem. IF you connect to the ftpd from the same machine where the server is running there is no problems, but if you connect from another pc to it does this:
ncftp / > ls
Data connection timed out.
Falling back to PORT instead of PASV mode.
It works, but it takes some time. I haven't been able to figure out the problem why the PASSIVE mode fails when connecting from outside.
This is his firewall:
this is his proftpd.conf
