Use ipchains. ftp is port 21. Example:
/sbin/ipchains -I input -p tcp -s 0.0.0.0/0 \
-d your.ip.add.ress 21 -j REJECT
/sbin/ipchains -I input -p tcp -s ok.ip.add.ress \
-d your.ip.add.ress 21 -j ACCEPT
0.0.0.0/0 is the entire world. For more info; man ipchains.
For a great site to start out at try:
