Pagi-pagi dikantor saya sempatkan untuk mengupdate article, hehe sebenernya sih cuman buat note pribadi biar ga lupa, kali ini saya akan menuliskan tutorial membersihkan seluruh
Berikut ini comment nya.
service iptables stop iptables -F iptables --flush /sbin/iptables --flush service iptables save service iptables start service iptables reload
comment diatas berguna untul flush seluruh rule atau aturan yang kita terapkan, untuk mengecek kita bisa menggunakan command ini
iptables -L iptables --list iptables -L -v -n /sbin/iptables -L -v -n --line-numbers
nanti akan muncul seperti ini

dan jika kita ingin mengahapus filternya hanya beberapa dan tidak semua, bisa memasukkan command ini

jangan lupa untuk save, restart dan reload .
tutorial ini mungkin banyak kurangnya, namun sudah diterapkan di server saya berhasil 😀 so silahkan mencoba.
