## Iptables
|

|
||
### Огляд
|
||
|
||
`iptables` - це стандартний інструмент управління брандмауером для багатьох дистрибутивів Linux. Він дозволяє адміністраторам налаштовувати правила безпеки для захисту сервера.
|
||
```bash
|
||
#Delete curent rules and chains
|
||
iptables --flush
|
||
iptables --delete-chain
|
||
|
||
#allow loopback
|
||
iptables -A INPUT -i lo -j ACCEPT
|
||
iptables -A OUTPUT -o lo -j ACCEPT
|
||
|
||
#drop ICMP
|
||
iptables -A INPUT -p icmp -m icmp --icmp-type any -j DROP
|
||
iptables -A OUTPUT -p icmp -j DROP
|
||
|
||
#allow established connections
|
||
iptables -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
|
||
|
||
#allow ssh, http, https, dns
|
