Kalau topologi biasa, yang
menggunakan satu ethernet di proxy, kurang mantap. Tapi, dengan topologi 2 ethernet dan bukan bridge, jadi bikin mantap. Client memang di limit 128Kbps, tapi brosing-nya, enceeerrrr... kek sungai deli waktu lagi banjir. Delay Pools malah gak ada artinya... Kalau warnet menggunakan RB-750. Dengan 5 Port yang ada, yang terpakai jadinya 4 Port. Ether1-ISP, Ether2-ProxyIN, Ether3-ProxyOut, Ether4-LAN. Kalau setting ZPH di Squid-nya, aku gak perlu bahas lagi lah, banyak yang sudah bahas, nanti dibilang aku tukang copy paste pulak lagi, hahahah... Setting Squid, malah standard. gak perlu banyak bikin refresh segala macam, cukup dengan mengaktifkan ZPH, lalu transparent proxy, lalu ip yang di allowkan untuk mengakses proxy, Besar cache_dir, maximum cache size, average cache size, cache_mem. Itu saja.
Untuk penghitungan cache_dir, aku juga gak bahas, dah banyak yang tulis di blog. Lalu, di mikrotik, aku lebih banyak pakai queue tree.
Kalau pake queue simple sih terserah, mangle untuk cache hit juga seperti yang telah dibahas banyak orang. Lalu per client di mangle, lalu di queue tree di limit 128kbps dengan satu parent utama.
Sedangkan queue tree untuk proxy, parentnya langsung global-out. Nah, di Mikrotik seperti yang kuketik di atas tadi, ada 4 Port yang di pakai.
Contoh
IP Ether1-ISP=192.168.2.2/24
Ether2-ProxyIN=192.168.14.1/30
Ether3-ProxyOut=192.168.15.1/30
Ether4-LAN=192.168.1.1/24
DNS- mengiktui DNS ISP
Di Squid Proxy:
Ether1 = 192.168.14.2/30
Ether2= 192.168.15.2/30
Gateway=192.168.15.1
DNS- mengikuti DNS ISP.
Lalu yang di-masquerade adalah 192.168.15.0/30.
Pasti ada yang bingung kan.
Kenapa IP LAN range-nya 192.168.1.0/24, sementara IP Proxy 192.168.14.2/30 dan 192.168.15.2/30. Nah aku pasti jawab, tapi aku mo lihat, seberapa banyak orang yang tertarik membaca blog-ku ini. Aku sengaja gak jelaskan. Send me a message... Aku hanya tampilkan gambar aja untuk queue tree-nya \
(Setelah sekian lama gak ku tulis, ini lah jamunya)

Dari gambar di atas terlihat bahwa, untuk traffik selain game yang diberi nama warnet dibatasi 400kb saja. Dan dibagian queue-types dilimit 400kbps pcq.Sementara Proxy HIT terpisah dari queue traffik yang lain karena Cache HIT dibuat tidak dibatasi.
Di Proxy (Debian),
root@cache:~# iptables -t nat -nL
Chain PREROUTING (policy ACCEPT) target prot opt source destination REDIRECT tcp -- 192.168.1.0/24 0.0.0.0/0 tcp dpt:80 redir ports 3128

zph_option 136

Topologi ini udah banyak aku bikin di pelanggan warnet kami. Dan sudah menjadi standar dari ISP kami. Sudah aku coba pakai ClearOS, tapi karena ZPH gak ada, jadinya gak maksimal. Aku coba-coba upgrade sendiri squid-nya, tapi ilmu linux ku masih kurang :-D. Gatotlah (gagal total)... OS linux yang kupakai Debian 5 atau pun semua distro linux yang squid-nya udah support ZPH.
