Load Balancing Dengan Mikrotik

Setting Load Balancing dengan Menggunakan
Mikrotik, adapun gambaran simpel network nya adalah sebagai berikut :

Ether1 berhubungan dengan ISP1 (WLAN), Ether2 berhubungan dengan Speedy dan Ether3 untuk jaringan localnya..

Dengan menggunakan mikrotik ada 3 komponen utama yg digunakan untuk membuat Load balancing yaitu :

1. ip firewall nat
2. ip firewall mangle
3. ip route

Berikut lampiran konfigurasinya :

[admin@Mikrotik] > ip address print

Flags: X – disabled, I – invalid, D – dynamic

#   ADDRESS            NETWORK         BROADCAST       INTERFACE

0   192.168.1.2/24     192.168.1.0     192.168.1.255   to-speedy

1   192.168.0.99/24    192.168.0.0     192.168.0.255   local

2   203.190.41.xx/29   203.190.41.xx   203.190.41.xx   to-jatara

[admin@Mikrotik] > ip route  print

Flags: X – disabled, A – active, D – dynamic, C – connect, S – static, r – rip, b – bgp, o – ospf

#     DST-ADDRESS        PREFSRC         G GATEWAY         DISTANCE INTERFACE

0 ADC 192.168.0.0/24     192.168.0.99                               local

1 ADC 192.168.1.0/24     192.168.1.2                                to-speedy

2 ADC 203.190.41.xx/29   203.190.41.xx                              to-jatara

5 A S 0.0.0.0/0                          r 203.190.41.xx            to-jatara

[admin@Mikrotik] > ip firewall mangle print

[admin@Mikrotik] > ip firewall nat print

Flags: X – disabled, I – invalid, D – dynamic

1   chain=srcnat connection-mark=speedy action=src-nat to-addresses=192.168.1.2 to-ports=0-65535

[admin@Mikrotik] > ip dns print

primary-dns: 203.190.40.x

secondary-dns: 202.134.0.155

allow-remote-requests: yes

cache-size: 4096KiB

cache-max-ttl: 1w

cache-used: 90KiB

[admin@Mikrotik] > interface print

Flags: X – disabled, D – dynamic, R – running

#    NAME                                                                     TYPE

RX-RATE    TX-RATE    MTU

0  R to-jatara                                                                ether            0

0          1500

1  R to-speedy                                                                ether            0

0          1500

2  R local                                                                    ether            0

0          1500

Untuk membuat supaya ip gateway lokal bisa dijadikan DNS lokal maka
pengaturannya ada dibawah ini, dan yg perlu diperhatikan adalah yang
ada tulisan allow-remote-request : yes

admin@Mikrotik] > ip dns print

primary-dns: 203.190.40.x

secondary-dns: 202.134.0.155

allow-remote-requests: yes

cache-size: 4096KiB

cache-max-ttl: 1w

cache-used: 90KiB
