How to protect UDP services against DDoS attack?
Seems that Racknerd's DDoS protection has protected my server from a DDoS attack yesterday, but while the DDoS protection was active, the server was re-routed from Multacom to Voxility. I found only TCP connection were forwarded and all UDP & ICMP packets were dropped. While my web services survived the attack, all service using UDP such as game server went offline, which is sad. Is there any solutions for protecting UDP services?
