RHEL 6 question (Security, Firewall, and Network)

I have used RHEL 5.6, and have just installed RHEL 6.

I coul deasily disable the firewall, by going to System->Administration->Security

Or I could modify the network by going to System->Administration->Network

Now I see no way to do either through the GUI

Can someome please tell me how to disable the firewall from the GUI

and how to disable it from the console

(and perhaps help with the how to get to the network GUI ?

Thanks
