Menggunakan router board mikrotik RB493 dengan 5 interface WAN untuk
koneksi ke internet menggunakan speedy. Semua modem speedy diset router.
Pemodelan koneksi adalah sbb:
/interface ethernet
/ip adress
/ip adress
/ip route
Penjelasan:
/ip dns
/ip dns static
/system clock
/system ntp client
/system ntp server
/ip firewall filter
/ip firewall address-list
/ip firewall nat
/ip firewall mangle
Baris-baris rule mangle yang berwarna hijau itu ditulis secara otomatis melalui script yang akan dijelaskan nanti.
param
Saat router reboot script param di bawah ini akan dieksekusi:
deadgwdetection
Script ini dijalankan via schedule setiap 120 detik atau 2 menit
Sekarang aktifkan schedule untuk dua script di atas:
/system scheduler
- Load Balancing menggunakan NTH untuk trafik browsing (tcp port 80) dan PCC untuk trafik non browsing.
- Koneksi ke speedy dianggap tidak stabil dan perlu dibuat fail over sehingga jika salah satu speedy putus maka Load Balancing PCC dan NTH masih berjalan.
- Koneksi internet user (clients) ke tcp port 80 (browsing) akan dilewatkan server proxy.
- Koneksi internet server proxy akan melalui Load Balancing NTH.
- Koneksi internet user (clients) selain browsing di atas akan melalui Load Balancing PCC.

Penjelasan:
- Baris routing yang berwarna hijau ditulis secara otomatis oleh script.
- Koneksi dari router keluar (internet) akan melalui semua gateway yang hidup (dalam contoh di atas ada 5 gateway).
- Untuk deteksi koneksi internet masing-masing wan dilakukan dengan cara ping ke ip tertentu di mana routing ke ip tersebut sudah dibuat statik per wan.
- Untuk cek koneksi wan1 dilakukan dengan ping ke ip 202.134.1.10
- Untuk cek koneksi wan2 dilakukan dengan ping ke ip 202.155.0.20
- Untuk cek koneksi wan3 dilakukan dengan ping ke ip 125.160.0.97
- Untuk cek koneksi wan4 dilakukan dengan ping ke ip 202.154.1.2
- Untuk cek koneksi wan5 dilakukan dengan ping ke ip 202.154.0.15

Baris-baris rule mangle yang berwarna hijau itu ditulis secara otomatis melalui script yang akan dijelaskan nanti.
param
Saat router reboot script param di bawah ini akan dieksekusi:
# # script: param # # Jumlah koneksi wan :global nwan 5; # daftar ip internet yang dirouting secara statik :global ips "202.134.1.10,202.155.0.20,125.160.0.97,202.154.1.2,202.155.0.15"; # daftar ip wan atau gateway :global gws "192.168.1.1,192.168.2.1,192.168.3.1,192.168.4.1,192.168.5.1"; # nilai atau score untuk masing-masing wan :global scrs "2,4,8,16,32"; :global SCORE 0;
Variable score scrs untuk menyimpan nilai atau score per wan sedangkan SCORE untuk menyimpan status online semua wan:
- Nilai SCORE 0 berarti semua WAN tidak online.
- Jika WAN 1 online maka nilai SCORE menjadi bertambah 2.
- Jika WAN 2 online maka nilai SCORE menjadi bertambah 4.
- Jika WAN 3 online maka nilai SCORE menjadi bertambah 8.
- Jika WAN 4 online maka nilai SCORE menjadi bertambah 16.
- Jika WAN 5 online maka nilai SCORE menjadi bertambah 32.
- Jika semua WAN online nilai SCORE adalah 2+4+8+16+32 = 62.

Penjelasan:
- Pertama deteksi apakah koneksi fisik ke wan running atau tidak (baris 17).
- Kedua apakah melalui wan tersebut bisa ping ke tertentu (baris 20).
- Jika tidak bisa diping cek trafik received yang melalui wan tadi apakah melewati threshold atau ambang batas tertentu sehingga bisa dianggap wan ini online (baris 21).
- Jika salah satu di atas berhasil, no 2 atau 3, maka naikkan jumlah wan dan tulis link wan yang aktif (baris 23). Jika semua gagal tulis di log bahwa koneksi melalui wan ini down (baris 24).
- Agar tidak terlalu banyak output ke log, matikan untuk sementara fungsi ini di baris 28.
- Jika ada perubahan jumlah koneksi atau nilai SCORE (baris 29) maka buat baru baris-baris mangle (baris 30-31).
- Baris 34-46 menulis ip firewall mangle Load Balancing PCC untuk koneksi non browsing (tcp port 80) dari clients dan Load Balancing NTH untuk koneksi dari proxy.
- Baris 48-50 menulis routing default yang baru untuk mikrotik.
- Fungsi logging diaktifkan kembali di baris 52.
- Nilai SCORE dari jumlah koneksi sekarang disimpan (baris 53-54).
Sekarang aktifkan schedule untuk dua script di atas:
/system scheduler
add comment="" disabled=no interval=0s name=sch-param-startup on-event=param \
policy=read,write,test start-time=startup
add comment="" disabled=no interval=2m name=sch-deadgwdetction on-event=\
deadgwdetection policy=read,write,test start-date=jan/01/1970 \
start-time=00:00:10
untuk menyempurnakan Aksi Tipu Tipu tadi.. wajib kita tambahkan settingan ini..
heheh
