Any method can against SYN FLOOD ATTACK to DA server ?

DA server is easily attack by SYN FLOOD ATTACK , because the license is need to follow by WAN IP , that mean it is very difficult to protect DA server to against SYN FLOOD ATTACK .


I have allowed this code in firewall-kiss :
$IPTABLES -N syn-flood
$IPTABLES -A INPUT -p tcp --syn -j syn-flood
$IPTABLES -A syn-flood -m limit --limit 1/s --limit-burst 4 -j RETURN
$IPTABLES -A syn-flood -j DROP


but these code is very SLOWS DOWN WEB PAGE LOADS DRAMATICALLY!!! I am so tired :o :( :confused:

I am no idea to against SYN FLOOD ATTACK NOW . it is too serious .

:( Does anyone has any good idea on it ? or any good experience on it ?
