New LB 2 WAN

# ROS 6.4x.x
# Sebelum copas ke terminal, ubah nama interface pada ether arah lan menjadi "LAN"
# Pastikan ISP 1 berada pada ether1
# Pastikan ISP 2 berada pada ether2
# buat route ke ISP 1 dengan mark routing to_isp1
# buat route ke ISP 2 dengan mark routing to_isp2
# buat default route dengan gateway isp 1 dan 2
# script ini untuk 2 WAN dan menggunakan ip 192.168.100.1 sebagai gateway ISP 1, 192.168.200.1 sebagai gateway ISP 2
# untuk memudahkan penyesuaian ip gateway gunakan "find replace"
