[QUESTION~] DDOS ATTACKS

[Fortera Global]

Hello, actually what is the best host for prevent ddos?
Cuz the OVH dont stopping the attacks (my friend got attacked every day and ovh dont working for prevent these ddos, like on bug on network from ovh)..
What rules on firewall is good and IPTABLES?
Linux

thanks

iptables will never help you simply because of the way Internet works. When packets get to your server, it's already too late, it doesn't matter if your iptables firewall drops them or not.
OVH can be effective if configured properly, I use them too.

Could you help with this? Many ADMS are being blackmailed because they do not know how to properly configure the firewall.
This is one of the worst things there is. The adm spends he spends and can not solve, always remaining in the attackers' hands.
Please?

PS. The attacks are peoples Br's ever.

I can't possibly help everyone with this problem on their servers. If you're under attack, I can offer you immediate test period on my hosting service to see if that would help with the attacks. Other than that, it all depends on a lot of factors: the server you have with OVH, how you configure it, the services you run on the server and their configuration. It's a lot of many details.

In my case, using one dedicated server gamer, Intel(R) Core(TM) i7-4790K CPU, 4.00GHz - Cores : 8 -Cache : 8192KB -RAM 4x 8192MB
HD 2 x 240 GB.

Firewall rules:

Accção = action, Autorizar = Authorize, todos = all, porta de destino = Destination port, Opções = Options

I'm using apache port 80, SSH port 22, ports game: 7171, 7172, 7173, 7575 (MageBot) and mysqlport..
I'm using only the programs: TFS and apache2 only

You should also drop ICMP (all of it) and see if it helps. Also check CPU usage of Apache, it may overload your server easily (I prefer nginx).
You can even drop all "IP" traffic if you'd prefer too.

Yes, that configuration seems good. Most DDoS attacks target port 80, so if you're under attack, you may want to kill port 80 (remove the allow rule) temporarily to see if that helps. Then you can consider hosting your website somewhere else. Remember there is CloudFlare too but you can't use TFS on the same domain you have CloudFlare on (you'd need to use a subdomain for OTS).

I receiving another attacks, when they attack my website stay online (normal), only game server got lags/kicks/disconnects all time. CPU usage 20%

Another thing you can do is to use netstat and see what IPs are attacking you. If it's not a distributed attack but only from a single IP or a few, you can add those manually to drop on OVH Firewall. If there are hundreds of them you are out of luck and need to think of something else.

When I being attacked my ssh turn offline and I cant do nothing.
