Game or Advance dedicated server for a TCP game?

[icy adder]

Hi, I have been hosting on OVH for a while now but never tested dedicated servers. I have a game which I am planning to host which only use TCP and its not listed on the supported game on the game firewall.

I have been reading about game firewall and its benefits and I notice that it does benefit UDP more. The dilemma I have is that what should I get if I where to host a game that uses only TCP?

before I use VLE-16 and I suffered a really really bad DDOS attack, I followed the ovh documentation with edge firewall but I think it's the limitation of VLE-16.

Generally, I would suggest that if your Game does not have any specific Filter applicable on the GAME range, then go with Advance.

hi @dusty zodiac, thank you for the suggestion, should I just follow the documentation of OVH about edge firewall or is there a better edge firewall settings that I can implement.

The ports that my game server use are

Port 80 - for website
443 - https
6900 - Login Server
6121 - Character Server
5121 - Map Server
8888 - Web Server
3306 - MySQL

before I suffer from SYN flood which makes our server freeze and disconnect everyone.

SYN flood is fairly difficult to 100% prevent from a Provider that the anti-DDoS is Stateless, so there's some setup you'd Ideally do on your side, (SYN rate limits per src IP/Range, other stateful filtering applications or XDP/eBPF programs to attach to the NIC directly).

and then minimize any ports available to public, if your SQL/Map servers for example do not need to be acessible to the public and is only connecting through the game itself locally, you could drop those, since it'd be used Localhost side.

if your current VLE VPS was never Saturated ( 2 Gbps down/uplink), then you may be able to implement something server-side to prevent these floods.
