3G Multi WAN

ALAT & BAHAN
- Router yg ane gunakan adalah huawei hg553
- Modem yg ane gunakan adalah vodafone/huawei k3715 & huawei e153
- Kartu yg digunakan keduanya tekomsel flash
- USB HUB abal2 kisran harga 10-15rb :hammers (kabel sudah diganti untuk menghindari daya yg kurang pada USB HUB, sehingga tidak perlu mempergunakan adaptor untuk menambah daya di USB HUB :) )

ane yakin bs juga di terapkan pada semua roter dengan syarat
1. firmware yg digunakan openwrt
2. ada slot USB dengan USB HUB
3. 2 modem bs langsung terdeteksi dengan baik tanpa perintah tambahan.

langsung aja ya tanpa basa basi

TAHAP KE LIMA
masuk ke "putty"

- Buat file, dengan perintah:

# chmod 755 /bin/tester.sh

- copas tulisan di bawah ini ke dalam file /bin/tester.sh

tester.sh
#!/bin/sh
if ! ping -q -c 1 -W 10 -I 3g-wan 8.8.8.8 > /dev/null; then
(ifup wan; sleep 5; /etc/init.d/multiwan restart) &
fi

if ! ping -q -c 1 -W 10 -I 3g-wan2 8.8.8.8 > /dev/null; then
(ifup wan2; sleep 5; /etc/init.d/multiwan restart) &
fi

kembali masuk ke "putty"
- ketik perintah:

# /etc/init.d/cron stop
# echo "*/2 * * * * /bin/tester.sh" >> /etc/crontabs/root
# /etc/init.d/cron enable
# /etc/init.d/cron start

SELESAI...............

# silahkan ubah config di atas sesuaikan dengan jenis roter, ISP yg dpergunakan dan posisi terdeteksinya modem di router
