Re: iptables service in ubuntu 14.04
There is no such thing as an iptables service. The netfilter stuff (iptables) is built into the kernel, with a great many of the possible add on components available as modules (at least under the usual Ubuntu kernel configuration).
ufw is just a front end for iptables, and yes it will leave the iptable rules if you turn it off. As mentioned by ajgreeny, you can flush the rule set and set default policies via:
Code:
sudo iptables -P INPUT ACCEPT
sudo iptables -F INPUT
sudo iptables -P OUTPUT ACCEPT
sudo iptables -F OUTPUT
sudo iptables -P FORWARD ACCEPT
sudo iptables -F FORWARD
sudo iptables -t nat -F
Or just re-boot after permanently disabling ufw (which I do not know how, because I do not use ufw).
Any follow-up information on your issue would be appreciated. Please have the courtesy to report back.
