Simple Load Balancer using IPTables
Konfigurasi Linux agar berfungsi sebagai router.
sysctl -w net.ipv4.ip_foraward = 1
sysctl -w net.ipv4.ip_foraward = 1
Mengkonfigurasi IPTables
iptables -t nat -A PREROUTING -p tcp -i eth1 --dport 80 -m state --state NEW -m statistic --mode nth --every 2 --packet 0 -j DNAT --to-destination 192.168.2.2:80
iptables -t nat -A PREROUTING -p tcp -i eth1 --dport 80 -m state --state NEW -m statistic --mode nth --every 2 --packet 1 -j DNAT --to-destination 192.168.2.3:80
Jangan lupa konfigurasi di chain FORWARD jika default chain FORWARD nya drop.
