Help Iptables + OVH firewall

[shakazulu]

Hello people. I have some problems on my dedicated server on OVH.

I'm getting attacks, and I do not know what type they are.

More than one here must have safe ovh, and I need if any can give me a help with the configuration of the network firewall and IP-Tables to reduce attacks, since ovh offers defense against DDOS but not against two.

I post some picks.

 

and here is the pic of the atack.
