Thread: .:.Loadbalance PCC + External Proxy +Automatic by pass Proxy

Assalamualaikum Wr.Wb

Setelah sekian lama absen, gw coba bikin tutorial ke 2 gw mudah2 an ga repost ya gan yg pasti dah dapet izin sama penunggu forum ini gan . Sesuai judul nya, Load balancing PCC + Proxy EXternal + Autmatic By pass Proxy Jika Down. Loadbalancing Versi gw ini hasil modifikasi dari berbagai sumber. jadi kalau ada kesamaan mangle dan nat mohon di maklumi ya. Bagi yg udah paham mohon masukannya bagi yg mau coba mohon review nya, karena tanpa kalian LB PCC ini ga akan tau kelemahan dan kelebihannya. OK . Kuliah subuhnya sampe sini sekarang kita mulai acaranya berikutnya

Berangkattttt

Yang Namanya Loadbalancing kayanya ga mungkin bisa ga ada mangle Rule di sini sakral.Wajib Hukumnya jadi ga boleh di tinggalkan apalagi di langgar

Kalau Khusyu pasti hasilnya juga bener, dapet keq begini



NAT

NAT atau bahasa ilmiahnya Network Address Translation ini juga sangat penting di dalam proses Loadbalancing karena Rule ini lah yg mengatur Interface dan IP yg di tuju. jadi gw harap jangan sampe lupa NAT

Begini Pasal 8 ayat 5 tahun 2010

chain=srcnat action=masquerade out-interface=Telkom comments="NAT LOKAL"
chain=srcnat action=masquerade out-interface=Telkom-1

chain=dstnat action=dst-nat to-addresses=192.168.4.2 to-ports=3128 protocol=tcp src-address-list=IP Users dst-address-list=!IP Proxy dst-port=80,81,8080,3128 comments=TRANSPARANT SQUID"

chain=dstnat action=dst-nat to-ports=53 protocol=tcp in-interface=Lokal dst-port=53 comments="TRANSPARENT DNS"
chain=dstnat action=dst-nat to-ports=53 protocol=udp in-interface=Lokal dst-port=53
chain=dstnat action=dst-nat to-ports=53 protocol=tcp in-interface=Squid dst-port=53
chain=dstnat action=dst-nat to-ports=53 protocol=udp in-interface=Squid dst-port=53

rule ini khusus bagi yg memakai DNS server di squid proxy nya.

chain=dstnat action=dst-nat to-addresses=192.168.4.2 to-ports=53 protocol=tcp in-interface=Squid dst-port=53 comments="TRANSPARENT BIND9"
chain=dstnat action=dst-nat to-addresses=192.168.4.2 to-ports=53 protocol=udp in-interface=Squid dst-port=53

Hasil Foto di tekape



mudah2 an di jalan yg benar ya semua nya

Kalau tahap ini dah lewat berikutnya

ROUTE

bahasa gampangnya arah tujuan , ya begitulah pokoknya

langsung aja ya



berikut tambahan buat poker dan point blank karena di mangle sudah ada rule nya jadi biar ga tersesat gw tampilin sekalian pelaku nya

keterangan dari pelaku

chain=forward action=add-dst-to-address-list protocol=tcp address-list=Poker + PB address-list-timeout=0s dst-port=843 comments="SCANNER POKER + POINT BLANK"
chain=forward action=add-dst-to-address-list protocol=tcp address-list=Poker + PB address-list-timeout=0s dst-port=9339

chain=forward action=add-dst-to-address-list protocol=tcp address-list=Poker + PB address-list-timeout=0s dst-port=49100
chain=forward action=add-dst-to-address-list protocol=udp address-list=Poker + PB address-list-timeout=0s dst-port=40000-40010

BAP



lagi nyari scriptnya ya..dah mau kabur aja gw

scrpt ini untuk keadaan di mana proxy external mati/mokat/tewas/wafat yg disebabkan karena banyak hal*

* kecuali error - contohnya hdd badsector ..pengalaman pribadi

;;; MANGLE PROXY
192.168.4.2

add comment="MANGLE PROXY" disabled=no down-script=
\nip fi na en num=3\r\
\nip fi ma en num=22\r\
\nip fi ma en num=23\r\
\nip fi ma en num=24\r\
\nip fi ma dis num=19\r\
\nip fi ma dis num=20\r\
\nip fi ma dis num=21\r\
\nip proxy set enable=yes\r\
\n" host=192.168.4.2 interval=1s timeout=1s up-script="ip fi na en num=2\r\
\nip fi na dis num=3\r\
\nip fi ma dis num=22\r\
\nip fi ma dis num=23\r\
\nip fi ma dis num=24\r\
\nip fi ma en num=19\r\
\nip fi ma en num=20\r\
\nip fi ma en num=21\r\
\nip proxy set enable=no\r\
\n"

UPDATE

Rule ini untuk Yang memakai PCBOX untuk routernya agar bisa automatis ke Proxy internal jika proxy down bisa nambahin script ini di NAT
;;; AUTOMATIC ENABLE IF PROXY DOWN ---> Redirect to internal proxy | monitoring by netwatch
chain=dstnat action=redirect to-ports=3128 protocol=tcp
routing-mark=!jalur-1 src-address-list=IP Users dst-port=80,81,8080,3128
connection-mark=!ADSL-1



enaknya langsung bener apa gw salahin dulu ya biar bisa ga asal copas akangange mode : on

ok. demikian yg bisa sampaikan pada kesempatan kali ini mudah2 an berguna bagi nusa bangsa dan mempererat tali persaudaraan demi persatuan dan kesatuan di negara Ketuhanan yang maha esa.
