routed option can not be activated

Asked by RobertRobert


I want to use (g)ufw to block all traffic on all interfaces BUT ppp0 (which is my VPN)
I tried to activate the routed option like explained in the documentation:

I uncommended /etc/ufw/sysctl.conf:

And I did sudo ufw reload but no arrow around the shield.

I also tried "DEFAULT_FORWARD_POLICY="ACCEPT"" in "/etc/default/ufw" and "sudo service ufw restart"
(because of: )

I did reboots in between the steps. No arrow around the shield and the "interface" option in the "advanced" tab stay grey.
What can I do?

Thank you!

Hi :)
You need to use Gufw 14.10, Gufw 14.04 hasn't the IP forwarding.

Download the official package from here:
and install:
sudo dpkg -i gufw_14.10.1-0ubuntu2_all.deb

Don't worry, I development Gufw 14.10 in Ubuntu 14.04, then it has to work.

Could you confirm me if all works? :)
Best regards!
