[ubuntu] internet connection sharing via network manager

view story

http://ubuntuforums.org – I just setup internet connection sharing with the network manager on my laptop with ubuntu 12.10 and a wireless internet connection on eth1, so that it is sharing the connection through eth0, an ethernet port. It works, but the ip address given to the client (another ubuntu 12.10 machine) is How can I change this? I have setup internet connection sharing manually before, with ip masquerading, a static ip on eth0, and dhcp, and I would like to know if the same amount of control is possible through network manager.
