How do I configure ufw to only allow outgoing/established connections for a IPv6 network?
I am using an old computer with 12.04 installed to create an IPv6 router for my local network. I would like it to act as a firewall as well.
I have a tunnel setup and working with Hurricane Electric and the computer is successfully routing traffic to and from the IPv6 Internet.
I have followed the instructions given at https://wiki.ubuntu.com/IPv6#Configure_your_Ubuntu_box_as_a_IPv6_router under the “ufw and Routing” section.
Unfortunately, when I enable ufw, all connectivity is lost.
I'm also not sure what is meant by
If you only want outgoing connections you also need to change DEFAULT_FORWARD_POLICY="DROP"
Does that mean change it to equal “DROP” or change it to equal something else?
