Setting Mikrotik dan Squid Proxy External Full Versi

di sini ada postingan untuk mensetting mikrotik dan squid external,,
yuk ikuti langkah di bawah ini

Alat Yang di Gunakan :
- Modem Speedy
- RB750 ROS 4.6 atau Mikrotik v5.xx
- Squid proxy yang berjalan transparant pada port 3128 + zph

Topologi :
- Speedy 2M down dan 512 up
- 1M untuk jatah download semua client dengan batasan maksimal 256kbps/client
- Akses tanpa dibatasi limit untuk beberapa IP tertentu (dalam hal ini IP 192.168.2.16 dan 192.168.2.17)
- Browsing tidak dibatasi
- Aplikasi QOS pada outbound/paket yang keluar dari modem speedy

Manifest IP address yang digunakan :
[MODEM]
Public IP Address = 192.168.1.2/24
[CLIENTS]
Client IP Address = 192.168.2.2-192.168.2.17 (ip selain itu tidak konek internet)
[SQUID BOX]
Proxy Ip Address = 192.168.3.2
squid.conf dengan zph
http_port 3128 transparent
zph_mode tos
zph_local 0x30
zph_parent 0
zph_option 136

================Basic Configuration================

add address=192.168.2.2-192.168.2.17 comment="" disabled=no list=localNet
(saya hanya menjalankan client konek internet 2-17 client)

=================end of basic configuration=================

Untuk firewall filternya saya terapkan yang terpentingnya saja.

Untuk NAT nya sebagai berikut :

/ip firewall nat
add action=masquerade src-address-list=localNet chain=srcnat comment="NAT-LOCAL" disabled=no \
out-interface=Public
add action=masquerade src-address-list=ProxyNet chain=srcnat comment="NAT-PROXY" disabled=no \

dst-address-list=!ProxyNET dst-port=80,8080,3128 in-interface=Local \
protocol=tcp to-addresses=192.168.3.2 to-ports=3128

(atau yang saya punya redirect proxy seperti ini :)

add action=dst-nat chain=dstnat comment="TRANSPARENT PROXY" disabled=no \
src-address=192.168.2.2-192.168.2.17 dst-port=80,8080,3128 in-interface=Local \
protocol=tcp to-addresses=192.168.3.2 to-ports=3128
add action=dst-nat chain=dstnat comment="TRANSPARENT DNS" disabled=no \
dst-port=53 in-interface=Local protocol=udp to-ports=53
add action=dst-nat chain=dstnat comment="" disabled=no dst-port=53 \
in-interface=Local protocol=tcp to-ports=53
add action=dst-nat chain=dstnat comment="" disabled=no dst-port=53 \
in-interface=Proxy protocol=udp to-ports=53
add action=dst-nat chain=dstnat comment="" disabled=no dst-port=53 \
in-interface=Proxy protocol=tcp to-ports=53

Penjelasan :

- Transparent DNS agar client tidak bisa menggunakan NS selain yang terpasang di mikrotik

  (bisa sobat gunakan atau tidak, tergantung keinginan)

- Mengarahkan request dari client tujuan port 80,8080,3128 ke squid external

  saya beri contoh 2 untuk redirect terserah sobat mo pilih yang mana pastinya keduanya jalan

  jika ada interface lain misalkan hotspot sobat tingal tambahkan tanda ! pada src.address atau   dst.address list

Untuk manglenya biar saya jelaskan satu-persatu biar tidak bingung :

/ip firewall mangle

Menandai paket protocol tcp yang diteruskan ke client untuk memberikan batasan download pada masing-masing client dengan conn-byte=131072-4294967295

Setelah itu buat queue type nya

/queue type
add kind=pcq name=pcq_up pcq-classifier=src-address pcq-limit=200 pcq-rate=0 \
pcq-total-limit=8000
add kind=pcq name=pcq_down pcq-classifier=dst-address pcq-limit=200 pcq-rate=\
0 pcq-total-limit=8000
add kind=pfifo name=pfifo-critical pfifo-limit=10
add kind=pcq name=pcq_critical.up pcq-classifier=src-address,src-port \
pcq-limit=20 pcq-rate=0 pcq-total-limit=500
add kind=pcq name=pcq_critical.down pcq-classifier=dst-address,dst-port \
pcq-limit=20 pcq-rate=0 pcq-total-limit=500

di lanjut menambahkan queue tree nya…..

/queue tree
add burst-limit=0 burst-threshold=0 burst-time=0s disabled=no limit-at=0 \
max-limit=0 name="A. PROXY HIT" packet-mark=proxy-hit parent=Local \
priority=1 queue=default
add burst-limit=0 burst-threshold=0 burst-time=0s disabled=no limit-at=0 \
max-limit=0 name="B. CRITICAL" packet-mark=critical_pkt parent=Public \
priority=1 queue=pfifo-critical

Tanpa limit dengan prioritas pertama untuk proxy hit dan critical

add burst-limit=0 burst-threshold=0 burst-time=0s disabled=no limit-at=0 \
max-limit=0 name="C. INBOUND" packet-mark=all.post_pkt parent=global-out \
priority=8
add burst-limit=0 burst-threshold=0 burst-time=0s disabled=no limit-at=0 \
max-limit=0 name="D. OUTBOUND" packet-mark=all.pre_pkt parent=Public \
priority=8

Membuat parent untuk inbound (traffic masuk ke client) dan outbound (traffic keluar dari public)

Untuk child INBOUND nya saya bagi menjadi beberapa prioritas seperti berikut :

add burst-limit=0 burst-threshold=0 burst-time=0s disabled=no limit-at=0 \
max-limit=0 name="A. GAMES" packet-mark=games_pkt parent="C. INBOUND" \
priority=2 queue=pcq_critical.down
add burst-limit=0 burst-threshold=0 burst-time=0s disabled=no limit-at=0 \
max-limit=0 name="B. HTTP" packet-mark=browsing_pkt parent="C. INBOUND" \
priority=3 queue=pcq_down
add burst-limit=0 burst-threshold=0 burst-time=0s disabled=no limit-at=64k \
max-limit=128k name="C. REALTIME" packet-mark=realtime_pkt parent=\
"C. INBOUND" priority=4 queue=pcq_critical.down
add burst-limit=0 burst-threshold=0 burst-time=0s disabled=no limit-at=64k \
max-limit=128k name="D. FILETRANS" packet-mark=communication_pkt parent=\
"C. INBOUND" priority=5 queue=pcq_down
add burst-limit=0 burst-threshold=0 burst-time=0s disabled=no limit-at=64k \
max-limit=128k name="E. NORMAL" packet-mark=normal_pkt parent=\
"C. INBOUND" priority=6 queue=pcq_down

selanjutnya parent untuk download per client nya :

add burst-limit=0 burst-threshold=0 burst-time=0s disabled=no limit-at=0 \
max-limit=1024k name="F. DOWN 1M" parent="C. INBOUND" priority=8
add burst-limit=0 burst-threshold=0 burst-time=0s disabled=no limit-at=0 \
max-limit=0 name="G. DOWN 2M" parent="C. INBOUND" priority=8

membuat 2 parent untuk 1M dan 2M (atau tanpa limit)

Setelah itu buat child nya, untuk memberikan batasan download per clientnya

add burst-limit=0 burst-threshold=0 burst-time=0s disabled=no limit-at=0 \
max-limit=256k name=Client1 packet-mark=client1 parent=\
"F. DOWN 1M" priority=8 queue=pcq_down
add burst-limit=0 burst-threshold=0 burst-time=0s disabled=no limit-at=0 \
max-limit=256k name=Client2 packet-mark=client2 parent=\
"F. DOWN 1M" priority=8 queue=pcq_down

…………………..dst sampai semua paket ke client yang di perlukan terpenuhi

Batasan download sebesar 1M untuk semua client dan maksimum 256k per client

add burst-limit=0 burst-threshold=0 burst-time=0s disabled=no limit-at=0 \
max-limit=0 name=Client16 packet-mark=client16 parent=\
"G. DOWN 2M" priority=8 queue=pcq_down
add burst-limit=0 burst-threshold=0 burst-time=0s disabled=no limit-at=0 \
max-limit=0 name=Client17 packet-mark=client17 parent=\
"G. DOWN 2M" priority=8 queue=pcq_down

Tanpa batasan download untuk IP 192.168.2.16 dan 192.168.2.17

Kemudiam membuat limit untuk uploadnya

add burst-limit=0 burst-threshold=0 burst-time=0s disabled=no limit-at=0 \
max-limit=0 name="A. GAMES UP" packet-mark=games_pkt parent="D. OUTBOUND" \
priority=2 queue=pcq_critical.up
add burst-limit=0 burst-threshold=0 burst-time=0s disabled=no limit-at=64k \
max-limit=256k name="B. HTTP UP" packet-mark=proxy_pkt parent=\
"D. OUTBOUND" priority=3 queue=pcq_up
add burst-limit=0 burst-threshold=0 burst-time=0s disabled=no limit-at=32k \
max-limit=64k name="C. REALTIME UP" packet-mark=realtime_pkt parent=\
"D. OUTBOUND" priority=4 queue=pcq_critical.up
add burst-limit=0 burst-threshold=0 burst-time=0s disabled=no limit-at=64k \
max-limit=128k name="D. FILETRANS UP" packet-mark=communication_pkt \
parent="D. OUTBOUND" priority=5 queue=pcq_up
add burst-limit=0 burst-threshold=0 burst-time=0s disabled=no limit-at=64k \
max-limit=128k name="E. NORMAL UP" packet-mark=normal_pkt parent=\
"D. OUTBOUND" priority=6 queue=pcq_up
