Hentikan China dari koneksi ke server Google Compute Engine saya

11

Perusahaan saya memiliki server Google Compute Engine yang dihosting di Amerika Utara. Kami mendapatkan begitu banyak alamat IP Cina mengirimkan permintaan ke port 11 sehingga kami harus mengeluarkan biaya untuk itu. Firewall kami memblokir semua koneksi ke China karena mereka tidak memiliki bisnis yang memiliki akses ke aplikasi kami.

Apakah ada cara untuk sepenuhnya mengabaikan koneksi ini atau memblokirnya sedemikian rupa sehingga tidak akan memakan bandwidth?

Itu akan ada di Google, jika mereka ingin mendukungnya. Anda tidak dapat mengontrol apa pun di sisi lain dari port masuk Anda.

Mengapa port 11 terbuka sama sekali?

Google menagih Anda untuk lalu lintas ke port yang diblokir? Ya.

@TomTom Menurut cloud.google.com/compute/pricing#network lalu lintas masuk gratis. Selama port ditutup, seharusnya tidak ada jalan keluar untuk mengisi daya.

@ josh123a123 apakah Anda berhasil menurunkan biaya itu? Saya mengalami masalah yang sama

Firewall memiliki dua pilihan utama saat menerima upaya koneksi yang tidak diinginkan.

TOLAKAN - kirim tanggapan dengan mengatakan port / service / etc ditutup atau
tidak tersedia
JATUH - jangan merespons dan jatuhkan paket

Kata-kata Tolak / Jatuhkan tidak standar atau digunakan di semua firewall tetapi perbedaan antara konsep di balik dua tindakan yang mungkin akan ada di sana. Anda ingin melakukan yang setara dengan DROP sehingga tidak ada lalu lintas keluar. Seperti disebutkan oleh orang lain, lalu lintas masuk tidak dikenai biaya.

Tidak ada biaya untuk lalu lintas masuknya Mesin Komputasi Google. Lihatlah harga jaringan GCE . Jika Anda telah ditagih untuk lalu lintas masuk, Anda dapat menghubungi tim penagihan Cloud untuk mengklarifikasi dan memperbaiki biaya.

Mengenai permintaan ke port 11, sejauh port ini diblokir di firewall jaringan GCE Anda, instance VM Anda harus aman dan permintaan tidak boleh memakan bandwidth.

Saya ingin tahu cara Anda memonitor permintaan ini.

Saya melihat tagihan lagi dan tagihannya keluar. Saya menolak lalu lintas yang merupakan tempat bandwidth keluar dimakan.

Perhatikan bahwa tidak ada mode / pilihan TOLAK untuk GCE Firewall. Jaringan memeriksa aturan firewall yang memungkinkan koneksi ke target: jika demikian, ia mengirimkannya; jika tidak, itu hanya menjatuhkan paket tanpa memberitahu pengirim. Untuk informasi lebih lanjut, Anda dapat melihat bagian "Siapa yang Menangani Apa" dari artikel ini: cloud.google.com/compute/docs/networking#networkingdetails

Berikut adalah perintah cloud shell untuk menambahkan aturan firewall:
