FILE OVER 2 ISP & NETWATCH

ISP-A = 10.200.200.2/30 Gateway 10.200.200.1 (ether1)

ISP-B = 172.200.200.2/30 Gateway 172.200.200.1 (ether2)

LAN = 192.168.0.x/29 (ether3-LAN)

Konfgurasi IP Address

/ip address

add address=10.200.200.2/30 comment=ISP-A interface=ether1-wan1

add address=172.200.200.2/30 comment=ISP-B interface=ether2-wan2

add address=192.168.0.1/29 comment=LAN interface=ether3-LAN

Note : 

Untuk Ip ISP silahkan sesuaikan yang di dapat dari ISP 

Untuk nama interface di sesuaikan masing-masing

Konfigurasi NAT

/ip firewall nat

add action=masquerade chain=srcnat comment=ISP-A out-interface=ether1-wan1

add action=masquerade chain=srcnat comment=ISP-B out-interface=ether2-wan2

Konfigurasi Route

/ip route

add distance=1 gateway=175.200.200.1 routing-mark=Route-ISPA

add distance=1 gateway=103.200.200.1 routing-mark=Route-ISPB

add check-gateway=ping comment=recursive-ispa distance=1 gateway=8.8.8.8 \

    target-scope=30

add check-gateway=ping comment=recursive-ispb distance=2 gateway=8.8.4.4 \

    target-scope=30

add check-gateway=ping comment=chek-ispb distance=2 dst-address=8.8.4.4/32 \

    gateway=172.200.200.1

add check-gateway=ping comment=chek-ispa distance=1 dst-address=8.8.8.8/32 \

    gateway=10.200.200.1

Konfigurasi Mangle

/ip firewall mangle

add action=mark-connection chain=input in-interface=ether1-wan1 \

    new-connection-mark=Con-ISPA

add action=mark-connection chain=input in-interface=ether2-wan2 \

    new-connection-mark=Con-ISPB

add action=mark-routing chain=output connection-mark=Con-ISPA new-routing-mark=\

    Route-ISPA passthrough=no

add action=mark-routing chain=output connection-mark=Con-ISPB new-routing-mark=\

    Route-ISPB passthrough=no

Note : Konfigurasi mangle di fungsikan agar ketika ada trafick dari  ether1-wan1 baik masuk ataupun keluar akan melalui jalur yang sama  ether1-wan1, ketika ada trafick dari  ether2-wan2 baik masuk ataupun keluar akan melalui jalur yang sama  ether2-wan2.

Konfigurasi Netwatch

/tool netwatch

add down-script="/ip route disable [find comment=recursive-ispa]" host=8.8.8.8 \

    interval=3s up-script="/ip route enable [find comment=recursive-ispa]"

add down-script="/ip route disable [find comment=recursive-ispb]" host=8.8.4.4 \

    interval=3s up-script="/ip route enable [find comment=recursive-ispb]"
