Memisahkan gateway traffic Local dan International

Teknik lainnya utk memisahkan traffic data local/IIX dan International adalah dengan menggunakan mark-routing

Misal untuk traffic International dilewatkan melalui gateway 203.89.24.65 sedangkan traffic local Indonesia di lewatkan melalui gateway 203.89.24.177.

contoh konfigurasi IP address router user pada interface yang terhubung ke router Datautama

/ ip address
add address=203.89.24.66/27 network=203.89.24.64 broadcast=203.89.24.95 \
interface=ether1 comment=”ip point to point utk traffic lnternational” \
disabled=no
add address=203.89.24.178/30 network=203.89.24.176 broadcast=203.89.24.179 \
interface=ether1 comment=”ip point to point utk traffic local” disabled=no

Pertama masukkan daftar ip blok dari router NICE ke /ip firewall address-list seperti berikut:

/ ip firewall address-list
add list=nice address=58.65.240.0/23 comment=”” disabled=no
add list=nice address=58.65.242.0/23 comment=”” disabled=no
add list=nice address=58.65.244.0/23 comment=”” disabled=no
add list=nice address=58.65.246.0/23 comment=”” disabled=no
add list=nice address=58.145.174.0/24 comment=”” disabled=no
add list=nice address=58.147.184.0/24 comment=”” disabled=no
add list=nice address=58.147.185.0/24 comment=”” disabled=no
dst…

untuk mendapatkan script diatas dapat melalui URL berikut:

http://www.datautama.net.id/harijanto/mikrotik/ip_firewall_address_list_nice.php

Kemudian tandai packet data yang menuju local Indonesia

/ ip firewall mangle
add chain=postrouting dst-address-list=nice action=mark-routing \
new-routing-mark=nice passthrough=yes comment=”” disabled=no

Selanjutnya buat ip route berikut

/ ip route
add dst-address=0.0.0.0/0 gateway=203.89.24.65 scope=255 target-scope=10 \
comment=”traffic selain local Indonesia” disabled=no
add dst-address=0.0.0.0/0 gateway=203.89.24.177 scope=255 target-scope=10 \
routing-mark=nice comment=”traffic local Indonesia” disabled=no

Dengan demikian maka jika ke jaringan local Indonesia akan melalui 203.89.24.177 sedangkan untuk ke International melalui 203.89.24.65, sehingga jika interfacenya dipisah diantara router user dengan router datautama dapat diberi dua mikrotik sebagai bridge utk melimit traffic International maupun local secara terpisah.

Sedangkan disisi cisco router datautama dapat diseting seperti berikut:

 

interface FastEthernet0/1

description Interface yang point to point dengan International

ip policy route-map from-int-to-user

duplex auto

speed auto

!

interface FastEthernet1/1

description Interface yang point to point dengan IDC

ip policy route-map from-nice-to-user

duplex auto

speed auto

 

!

 

access-list 120 remark traffic dari luar ke user

access-list 120 permit ip any 203.89.26.0 0.0.0.255

!

route-map from-nice-to-user permit 10

match ip address 120

set ip next-hop 203.89.24.178

!

route-map from-int-to-user permit 10

match ip address 120

set ip next-hop 203.89.24.66

 

Jika ingin lebih baik maka di sisi user harus menggunakan router bgp, utk memisahkan traffic user menggunakan BGP akan dijabarkan pada artikel berikutnya.

Selamat mencoba.
