Problem with UDP attacks

[FNetissime]

Bonsoir,

I have a problem on my Pfsense with UDP attacks.

I have installed pfense in firewall mode, with 3 vlans in trunk mode, and if we have traffic more than 200k UDP packets/s , my pfsense system goes down and the traffic is immediately stopped.

Have you an idea of ​​the problem ?

Thank you.
Florian.
