Are you Blocking ipv6 traffic on your firewall?

New articles are up on uninformed. As always it is a good read. Especially an article from H D Moore (Creator of Metasploit Project) on ipv6. Check it out.

NOTE: On ubuntu ufw doesn't block ipv6 traffic by default and yes, ipv6 is enabled by default. :)

To disable IPv6 on Ubuntu Linux, open /etc/modprobe.d/blacklist in the editor of your choice and add the following lines to the end of the file:

# disable IPv6
blacklist ipv6

Now reboot for changes to take effect.
