[Icecast] Help attack DDOS

[Yahav Shasha]

Server software firewall cannot help with ddos attacks.
Basically if those are indeed ddos attacks you’ll have to look into
mitigation solutions which are quite expensive. CloudFlare won’t work as
well since they do not support streaming.
You should consider getting a server at a data center which provide ddos
mitigation, I know that OVH’s mitigation is quite good.
