Çin'in Google Compute Engine sunucuma bağlanmasını durdur

Şirketimin Kuzey Amerika'da barındırılan bir Google Compute Engine sunucusu var. 11 numaralı bağlantı noktasına istek gönderen çok sayıda Çin IP adresi alıyoruz, bu da bize giriş için paraya mal oluyor. Güvenlik duvarımız, uygulamalarımıza erişimi olmayan bir işi olmadığı için Çin'e olan tüm bağlantıları zaten engelliyor.

Bu bağlantıları tamamen görmezden gelmenin veya bant genişliğini tüketmeyecek şekilde bloke etmenin bir yolu var mı?

Güvenlik duvarları, istenmeyen bağlantı girişimleri alırken iki ana seçeneğe sahiptir.

1. REDDET - bağlantı noktasının / hizmetin / vb. Kapalı veya
   kullanılamadığını belirten bir yanıt gönderin
2. DROP - yanıt vermeyin ve paketleri bırakın

REJECT / DROP kelimeleri standart değildir veya tüm güvenlik duvarlarında kullanılmaz, ancak olası iki eylemin arkasındaki kavramlar arasındaki fark orada olacaktır. DROP eşdeğerini yapmak istiyorsunuz, böylece giden trafik yok. Diğerleri tarafından belirtildiği gibi gelen trafik hiçbir ücrete tabi değildir.

Google Compute Engine giriş trafiği için herhangi bir ücret alınmaz. GCE ağ fiyatlandırmasına bir göz atın . Giriş trafiği için ücretlendirildiyseniz, ödemeyi açıklığa kavuşturmak ve düzeltmek için Bulut faturalandırma ekibiyle iletişime geçebilirsiniz.

Bağlantı noktası 11'e yönelik isteklerle ilgili olarak, GCE ağınızın güvenlik duvarında bu bağlantı noktası engellendiği sürece VM örnekleriniz güvenli olmalı ve istekler bant genişliğini tüketmemelidir.

Bu istekleri nasıl izleyeceğinizi merak ediyorum.

Güvenlik duvarı kurallarını eklemek için bulut kabuğu komutları şunlardır:
