How do i enable or disable ipv6 on ubuntu ufw netfilter firewall?
-
Note: The default on later Ubuntu versions of ufw is enabled by default.
The /etc/default/ufw file is a high level configuration file, to change default policies, add IPv6 support and kernel modules.
$ vi /etc/default/ufw
Edit the section in file, change variable IPV6 to yes.
# Set to yes to apply rules to support IPv6 (no means only IPv6 on loopback # accepted). You will need to 'disable' and then 'enable' the firewall for # the changes to take affect.
IPV6=yes
For disable change the variable to
IPV6=no
As the description says the firewall needs to be disabled and then enabled to take affect.
