firewall udp flood

    Does anyone know how to create plesk firewall rules to disable UDP except for needed services such as DNS (53)?

    I've tried deny all outgoing udp + allow outgoing on 53, and this prevented the server from getting name resolutions.

    I need to do this to prevent my server from being used to attack other servers via UDP flood. Suggestions are appreciated.
