malformed tcp and udp with 0 port

This IRule working fine on Virtual server 

when CLIENT_ACCEPTED {
   

    # Drop packets with port 0 for both TCP and UDP
    if {[TCP::remote_port] == 0 || [TCP::local_port] == 0 || [UDP::remote_port] == 0 || [UDP::local_port] == 0} {
        drop
        return
    }
}

IRule are resource hungry, how can i apply this rule or policy at Global level or device at applies to all Virtual servers
