FTP connection refused to anonymous server

ftp

I am trying to connect to a public FTP server that allows anonymous connexions. The server is fr2.rpmfind.net and it works from my terminal

ftp fr2.rpmfind.net
Connected to mandril.creatis.insa-lyon.fr.

Now I have another terminal with SSH to a remote machine and for the same command this is what I get:

ftp: connect: Connection refused

How can I get a connection refused if FTP server allows anonymous connexions?

Try running a traceroute to the server from both site, checking to see if a router is blocking your connection at some point along the route.
