menggunakan mikrotik jg bisa untuk "load balancing" tinggal pasang 3 interface,
interface A untuk Speedy1 , misal IP 192.168.1.1
interface B untuk Speedy2 , misal IP 192.168.2.1
Interface C untuk LAN , misal IP 10.10.10.0/24
config di mikrotik sperti ini :
> /ip address add address=10.10.10.0/24 interface=LAN
IP address untuk SpeedyA :
> /ip address add address=192.168.1.1/32 interface=SpeedyA
IP address untuk SpeedyB :
> /ip address add address=192.168.2.1/32 interface=SpeedyB
Selanjutnya kita tentukan gateway dengan prioritas :
> /ip route add gateway=192.168.1.1,192.168.2.1,192.168.2.1
Bisa juga ditambahi config untuk failover, jd misal salahsatu speedy ada yg mati bisa langsung menggunakan speedy jalur satunya,
> /ip firewall mangle add chain=prerouting src-address=10.10.10.0/24 action=mark-routing new-routing-mark=RM-SPEEDY
> /ip route add gateway=192.168.2.1 routing-mark=rm-speedyB check-gateway=ping
> /ip route add gateway=192.168.1.1
Atau dg alternatif lainnya yakni, kita membagi traffik ke dua jalur speedy tersebut berdasarkan group network di LAN kita,
Kita setting IP di masing" interface mikrotik,
/ip address add address 192.168.1.1/32 interface speedyA
/ip address add address 192.168.2.1/32 interface speedyB
/ip address add address 10.10.10.1/24 interface LAN
Selanjutnya kita coba bagi network kedalam 2 Group
add chain=prerouting action=mark-connection src-address 10.10.10.0/25 new-routing-mark= Group-A
add chain=prerouting action=mark-connection src-address 10.10.10.128/25 new-routing-mark=Group-B
selanjutnya kita set default gateway masing-masing group
/ip route add gateway=192.168.1.1 routing-mark=Group-A
/ip route add gateway=192.168.2.1 routing-mark=Group-B
Pastikan juga kita udah setting NAT pada network kita
/ip firewall nat add chain=srcnat src-address 10.10.10.0/24 action=masquerade
Menggunakan 3 etrernet card
ether1 ==> wireless
ether2 ==> speedy
ethet3 ==> Lan
mikrotik command:
/ip address add address 202.152.74.1/32 interface ether1
/ip address add address 192.168.1.2/32 interface ether2
/ip address add address 192.168.10.1/24 interface ether3
Membagi Ip menjadi 2 Group
add chain=prerouting action=mark-connection src-address 192.168.10.0/25 new-routing-mark= Group-A
add chain=prerouting action=mark-connection src-address 192.168.10.128/25 new-routing-mark=Group-B
Default gw masing-masing Group
Group-A=192.168.10.0/25 default gw 192.168.1.1
Group-B=192.168.10.128/25 default gw 202.152.74.128
mikrotik command:
/ip route add gateway=192.168.1.1 routing-mark=Group-A
/ip route add gateway=202.152.74.128 routing-mark=Group-B
Nat ip local
192.168.10.0/24 ==>masquerade
mikrotik command:
/ip firewall nat add chain=srcnat src-address 192.168.10.0/24 action=masquerade
ip route add dst-address=0.0.0.0/0 gateway=192.168.1.1 check-gateway=ping
ip route add dst-address=0.0.0.0/0 gateway=10.0.148.254 check-gateway=ping
Dimana 192.168.1.1 router ADSL & 10.0.148.254 gateway RT/RW-net pake 2.4ghz dah cuma gitu aja sih ..
cek gateway pake ping jadi kalau gateway down
langsung switch. Kalau gak down ya langsung on 2 sekaligus, kayanya sih load balancing
cuma kebetulan saya tambah parameter distance=2 di gateway RT/RW-net jadi dapet prioritas lebih rendah ..
Firewall / NAT bikin dua biji untuk masing-masing gateway
untuk client sih gampang
add route default gw IP-ether-mikrotik
PC / Router mikrotik yang saya operasikan ada 3 LAN card
2 ke arah modem ADSL, 1 ke arah LAN
client di arahkan gatewaynya ke ethernet LAN mikrotik aja
Selamat mencoba dan Semoga sukses…. …
