SETTING MIKROTIK DAN SQUID PROXY FULL VERSI

Salam Blogger!!
Asa Bucat Bisul!!! orang sunda bilang ehehe, 2 hari saya tidak posting karena masih meneliti kinerja settingan mikrotik yang saya gunakan dan alhasil banyak penemuan penemuan baru ahahaha,. posting kali ini mungkin agak panjang nich masalah Setting Mikrotik dan Squid Proxy External Full Versi.
Settingan ini cocok untuk warnet atau penyedia hotspot menurut saya, tau menurut sobatmah ahahhaha. Settingan ini yang saya pake sekarang, Sudah siap untuk melihat dan menelitinya?
Ok Lanjuuuuuuuut.......!!!

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

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 \

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 \

add action=dst-nat chain=dstnat comment="" disabled=no dst-port=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 :

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

C a t a t a n
- Silahkan sobat sesuaikan Untuk IP ADDRESS, Nama Ethernet. dll
- Tanda Hijau Biru dan Merah sengaja saya tandai agar sobat tidak tertukar jika sobat sudah memberi nama lain (maksudnya harus di sesuaikan)
- Tanda Jingga da Ping harus sama dengan yang ada di address list (jika sobat mengganti dengan nama lain)
- Silahkan sobat Kopi script yang saya buat dan pastekan dahulu di notepad (maksudnya di di hilangkan keterangan-keteranganya, buat satu block satu block biar tidak pusing eheheh)

Diurutkan berdasarkan prioritas paket keluar, mulai dari games, http request, realtime connection, filetransfer dan normal request
Hasil akhir yang saya capai, masing-masing client tidak terganggu oleh aktifitas download ketika mereka browsing atau main games, baik pada saat user sedang upload pun tidak mengganggu/memperbesar latency games…. sependek pengetahuan saya soal mikrotik setelah beberapa kali uji coba, mungkin ini settingan terbaik yang pernah saya buat.
Semoga bermanfaat dan selamat mereset Mikrotiknya, succes!!!!
