How to enable IPv6 support
From Tech-Wiki
As of ScreenOS 6.2 IPv6 is supported in ScreenOS. It is however disabled by default.
In order to enable IPv6, the environment variable needs to set by the administrator.
set envar ipv6=yes
The firewall needs to then be is rebooted, at which point IPv6 will be enabled. To check this has been enabled run the command
get envar
You should see the following:
netscreen-> get envar ipv6=yes
To remove this behaviour the following command needs to be set by the root administrator:
unset envar ipv6=yes
Once again the firewall needs to be rebooted to change the firewall back to the default behavior.
