UDP flood detected for legitimate traffic

Hello,

 

I'm running vCMP with BIG-IP 11.6.0 Build 4.0.420 Hotfix HF4.

 

We've seen loot's of UDP flood attacks detected and we are having problems with VOIP and PCoIP going through device.

 

The problem is that the DDoS profile is disabled.

 

What to do now?

 

Bojan

    It was the setting under Security ›› DoS Protection : Device Configuration.

     

    UDP flood threshold was too low.

     

    Cheers!
