Another kind of firewall is active in your system

I am doing a fresh install of Opensuse 12.3. When I try to configure the firewall with Yast2 I get the message

Another kind of firewall is active in your system

I did not specify any kind of firewall when I installed so I don’t know what this means. The message does not indicate what the other firewall is.

Not long ago there was something like this: http://forums.opensuse.org/english/get-technical-help-here/applications/397759-firewall.html
Look ifthat helps.

This you are doing during the install?
Just leave it alone, it’s ON by default.

Otherwise - explain yourself more clearly.
