catatan : konfigurasi proxy karya http://hendraarif.web.id
Buat file porn.txt (isikan daftar situs porno yang tidak boleh diakses) dan letakkan di /etc/squid/
restart squid dengan perintah : /etc/init.d/squid restart
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
Restart Server dengan perintha : shutdonw -r now
Selanjutnya coba lakukan bowsing dari client…
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.
Selamat Mencoba.
