F15 connection sharing

[Pasha R]

I'm trying to figure out the connection sharing option in F15. I
connect to internet using PPPoE, and, till now, I used "old" network
configuration (and disabled network manager) to setup a static IP
address and PPPoE connection, and then used masquerading to share
connection to other computers on the network.
In F15 I can't find a way to make such configuration and also can't
find  an option in NM to enable connection sharing for DSL connection.
Is there anything I'm missing?
