catatan : konfigurasi proxy karya http://hendraarif.web.id

1. Buat file porn.txt (isikan daftar situs porno yang tidak boleh diakses) dan letakkan di /etc/squid/
2. restart squid dengan perintah : /etc/init.d/squid restart
3. Buat NAT dan Tranparan Proxy di /etc/rc.local dengan script berikut ini :
   echo 1 > /proc/sys/net/ipv4/ip_forward
   #iptables -t nat -A POSTROUTING -j MASQUERADE
   iptables -A PREROUTING -t nat -p tcp -s 192.168.1.0/24 -i eth1 -d \! 192.168.1.0/24 –dport 80 -j REDIRECT –to 8080
   iptables -t nat -A POSTROUTING -j MASQUERADE
   exit 0
4. Restart Server dengan perintha : shutdonw -r now
5. Selanjutnya coba lakukan bowsing dari client…
6. Gunakan perintah #tail -f /var/log/squid/access.log untuk melihat situs yang di akses oleh client. Jika ini berjalan berarti squid kita telah berhasil di buat.
7. Selamat Mencoba.
