Hello,everyone!

when I run the command "service iptables start", it returns the error: "Unit iptables.service failed to load: No such file or directory"
How to start iptables on Rpi2 based on raspbian?

Thanks!

Hi, I think iptables are built into the kernel for Raspbian.

Do you get an output when you type

Code: Select all

sudo iptables -L

?

Unless you are up to something really tricky, like making a router, using one of the wrappers for iptables is a boat load easier. I like ufw but the syntax is a little funky. What are you really trying to do?

[zfyseu]

I just want to add some rules of iptables like "iptables -A INPUT -p tcp --dport 80 -j ACCEPT", however when I reboot the RPi, the rules are missing.
How should I do ?

You could either install a package to set your IPTABLES rules persistent, or as knute mentioned, learn UFW.

Code: Select all

sudo ufw allow http
sudo ufw enable
sudo ufw status

I have solved the problem.

I worte a bash file executed automaticlly at boot time.

Another way maybe be "# apt-get install iptables-persistent" seen as the link http://blog.mxard.com/persistent-iptabl ... i-raspbian
