Linux: Reset iptables firewall rules
Create a shell script (iptables_flush.sh) and copy paste the following lines:
#!/bin/sh echo "Flushing iptables rules..." sleep 1 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
Make the file executable
chmod +x iptables_flush.sh
and run the script:
./iptables_flush.sh

There rules will lock down the machine and if you are connecting from a remote ssh session you wont connect.
I’d recommend these rules
# iptables -P INPUT ACCEPT
# iptables -F
# iptables -A INPUT -i lo -j ACCEPT
# iptables -A INPUT -m state –state ESTABLISHED,RELATED -j ACCEPT
# iptables -A INPUT -p tcp –dport 22 -j ACCEPT
# iptables -P INPUT DROP
# iptables -P FORWARD DROP
# iptables -P OUTPUT ACCEPT
# iptables -L -v
