Load Balancing for Dual ISP (Internet Service Provider)
this is the file /etc/pf.conf, with decription above
in_if=”rl0″ /*for internal network interface*/
ext_if0=”tun0″ /*external interface 1 connect to modem ADSL*/
ext_if1=”tun1″ /*external interface 2 connect to modem ADSL*/
ext_gw1=”125.163.xxxx.xxxx” /*gateway, setup by ISP*/
priv_addr=”192.16.1.0/24″
nat on $ext_if0 from $priv_addr -> $ext_if0
nat on $ext_if1 from $priv_addr -> $ext_if1
pass out on $in_if from any to $priv_addr
/*syntaks for load balancing*/
pass in on rl0 route-to { (tun0 $ext_gw1), (tun1 $ext_gw1) } round-robin proto tcp from $priv_addr to any keep state
/*syntaks for load balancing*/
pass in on $in_if route-to { (tun0 $ext_gw1),(tun1 $ext_gw1) } round-robin proto {icmp,udp} from $priv_addr to any keep state
pass in on rl0 proto tcp from $priv_addr to any port 22 keep state
pass in on rl0 proto udp from any to any port 161 keep state
pass out on $ext_if0 proto tcp from any to any keep state
pass out on $ext_if0 proto {udp,icmp} from any to any keep state
pass out on $ext_if1 proto tcp from any to any keep state
pass out on $ext_if1 proto {udp,icmp} from any to any keep state

load balancing
load balacing adalah sebuah konsep pembagian source pada koneksi ke ISP.
misalnya kita mempunyai 3 line pada ISP, dengan 3 line tersebut dijadikan menjadi 1 gateway, dengan logika prosesnya yaitu : client pada jaringan local yang berada di dalam gateway tersebut hanya mengenal 1 gateway, sedangkan jalan keluarnya terdiri dari 3 line, dengan cara memilih jalan yang masih kosong atau sedikit koneksi yang melewati line tersebut, sedangkan yang yang memilih line mana yang dipakai oleh client diatur oleh sistem dalam load balancing tersebut..
