How To List and Delete Iptables Firewall Rules

iptables -L INPUT -v

Reset Packet Counts and Aggregate Size

iptables -Z

Flush All Rules, Delete All Chains, and Accept All

    sudo iptables -P INPUT ACCEPT
    sudo iptables -P FORWARD ACCEPT
    sudo iptables -P OUTPUT ACCEPT

Then flush the nat and mangle tables, flush all chains (-F), and delete all non-default chains (-X):

    sudo iptables -t nat -F
    sudo iptables -t mangle -F
    sudo iptables -F
    sudo iptables -X
