You're right, after attempted again I managed to get it to login to my FTP server, but ftp was not the best protocol to try it on considering the way data back from the server is sent, which there's no way of fiddling.I'm not sure what you mean by this, but:
What I meant is to get any useful data back over the FTP DATA connection (for LIST, RETR, STOR commands, etc.) you either have to use a passive mode transfer in which case you need to get another connection to connect to an arbitrary port on the server. Or an active mode transfer in which case you need to be able to listen on a port specified in the PORT command. I believe this is a risk for tunneling back through firewalls as pointed out by others with the recent linux 2.4 iptables PORT problems. Barnaby
