terima kasih Pak Kurniadi atas responnya, jika menggunakan settingan saya di atas, pada saat menggunakan tailf /var/log/squid/access.log, memang akan terlihat situs yang dibuka, tetapi situsnya di denied semua. untuk perintah iptbales-save, ini maksudnya di save tanpa di reboot? kalau sya coba, saya tetap harus reboot untuk mengaktifkan settingan iptables. -- FAQ milis di http://wiki.linux.or.id/FAQ_milis_tanya-jawab Unsubscribe: kirim email ke [email protected] Arsip dan info milis selengkapnya di http://linux.or.id/milis
