I need to share my internet connection from wired lan to wireless lan but in knetwrokmanager there's no way to do it in simple way.
Let me show you to explain how this work on mac os x.
Mac os settings ask me the source of internet connection (wired in my case) and the distributor (wirless,called airport on mac).In addition I had to specify name of ad-hoc connection and security stuff.Then the system think on activate dhcp and to set all firewall rules.I don't own a mac but a time I saw this and it was too simple,hiding non-foundamental information as dhcp and firewall to user.It could be easy realizing the same with knetworkmanager including a expert-user section to specify dhcp and iptable rules.
