NetworkManager Bridges in Fedora

[Steve Dickson]

Hello,

Has anybody had any luck with getting bridges
consistently up in running in either F19 or F20?
I know I have not... 

I go into setup/networks. Add a bridge which creates 
two file in /etc/sysconfig/network-scripts

ifcfg-Bridge_connection_1
ifcfg-bridge0_slave_1

The contents seem reasonable. 

After I reboot, I go back in to setup/networks. The status
of the bridge is "connecting" and the Bridge slaves
are "none"???

Anybody know what has to happen to get this code working??

tia,

steved.

P.S. If there is a better list for me to ask this 
     question, please point me to it...
