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.
