Flush (reset) iptables rules

Sebaiknya dibuat script untuk melakukan flushing iptables agar dapat dieksekusi dilain waktu.

# vim /root/scripts/iptables-flush.sh
[-- SNIP --]
#!/bin/bash

echo "Flushing iptables..."
iptables -F
iptables -X
iptables -t nat -F
iptables -t nat -X
iptables -t mangle -F
iptables -t mangle -X
iptables -P INPUT ACCEPT
iptables -P FORWARD ACCEPT
iptables -P OUTPUT ACCEPT
[-- SNIP --]

# chmod +x /root/scripts/iptables-flush.sh
# /root/scripts/iptables-flush.sh
Chain INPUT (policy ACCEPT)
target     prot opt source               destination         

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination
