OS?

If linux you can manual block them with iptables
>> iptables -A INPUT -s 78.163.13.180 -j DROP
You'll need root access!

If you want to automate that, pls take a look @ "deflate"

Quote:
root@localhost:~/deflate# wget http://www.inetbase.com/scripts/ddos/install.sh
root@localhost:~/deflate# chmod 0700 install.sh
root@localhost:~/deflate# ./install.sh
root@localhost:~/deflate# vi /usr/local/ddos/ddos.conf
@.conf u can use
NO_OF_CONNECTIONS=60
APF_BAN=0 (set to 1 if u use APF)
KILL=1
mail=if u need ... if not dnt set.

and /usr/local/ddos/ddos.sh -c for autostart.

Peace.

any chances you can move to OVH?
otherwise there isn't much you can do besides blocking new connections during an attack and hoping the DDoS is not greater than your connection.

If it's A2S attack you can try setup:
1. SourceQueryCache service [https://github.com/blastehh/SourceQueryCacheMono]
2. Kernel redirection to SQC [https://forums.alliedmods.net/showthread.php?t=297237]

And servers will be protected.

Can you dump traffic and post here? You can use tcpdump
