Comment on How To Reset Linux Firewall Automatically While Testing Configuration With Remote Server Over SSH Session by Kevin Green

nice script, but you forgot the raw table
also, i think it would be a good idea to reset the counters and delete any existing empty chains
so

iptables -F
iptables -X
iptables -Z
iptables -t mangle -F
iptables -t mangle -X
iptables -t mangle -Z
iptables -t nat -F
iptables -t nat -X
iptables -t nat -Z
iptables -t raw -F
iptables -t raw -X
iptables -t raw -Z

cheers
