Hi

Depends on how they filter your FTP traffic. My guess is that they just
filter out port 21. In which case try to run a ftp server on a port
different than 21 (or if you cant admin the FTP server run a port
forwarder that knows to forward FTP traffic on another port to forward
traffic to the true FTP site, I think portfwd knows that, check on 
freshmeat.net).

Now if they filter it by looking into the traffic (string based, altghough 
that can be very resource consuming and risky business) then you need some 
encrypted tunnel. You might use SSH with portforwarding (btw you could use 
SCP to copy your files) or another encrypted tunneling like IPSEC, 
vtun (with kernel support).
