okay try these iptables rules as starting point, 

# Load the FTP connection state helper module.
#Clear \ Flush all the rules from the different chains and tables
for table in mangle nat filter; do
   iptables -t $table -F
   iptables -t $table -X
done
# Set the default filter table policy
iptables --policy INPUT   DROP
iptables --policy OUTPUT  ACCEPT
iptables --policy FORWARD DROP

# Using Connection State to By-pass Rule Checking
iptables -A INPUT  -m state --state ESTABLISHED,RELATED -j ACCEPT
iptables -A INPUT -p tcp -m multiport --dport 25,80,21,22,23 -m state
--state NEW -j ACCEPT

Note: save these rules to a file, then chmod +x the file and then
execute it with ./filename :)

regards
