Ok, let me do the transfers at least in PSV, don't loose the connection RANDOMLY on EVERY computer and connecting on EVERY ftp server! Well, that's unfair, I paid 150eur and it's a crap stuff.

It would be Apple who made one problem in life for NAT-cloistered FTP servers easier. NAT is a right arse, and this sort of crap won't go away - really go away - till we move to IPv6 (and that's one thing your pretty box gets right, so think before trashing it). For the record: there is a server FTP ALG, and to enable it you *only* map port 21 into your server. If traffic passes to port 21, it goes through the Airport ALG. NAT makes the passive mode problematic on server only (you obviously know your networking), so the ALG changes the address and port number to a temporary, mapped port to make the private address and port announced reachable. There are other ALGs in there to make other changes, but some of them are broken. So yeah, if it weren't for UPnP, think before throwing it out, and hope and pray for IPv6. Cheers, Sabahattin PS: Change the LED from flashing to steady? Restart! :-) It's ironic, since NAT-PMP portmaps happen without restarts. Perhaps you'll look into Lighthouse? I won't.

I can only set filezilla in PSV, but it losts the connection every time and the first time it needs several times in order to connect to the ftp server (at least 7 8 times).

Configure your FTP server to NOT try and determine the external IP, and just listen on the internal IP. The Airport will (should) handle the rest. @flapane – Just let the Airport handle the Passive port translation.
