NetworkManager is getting support for bridging. It is not yet in the master branch (as of 2012-06-14) and it doesn't yet work for me (pavlix) but I believe it's time to have some testing configuration to work with. It may not work for you, so feel free to modify this page when bridging support is generally available.
== The 'keyfile' way
Bridge:
[connection] id=Bridge uuid=fc61f6e5-8900-4c6f-915c-eb55714eb874 type=bridge [bridge] interface-name=wan2
Slave:
[connection] id=Slave uuid=2e1906b1-92a4-4206-b2d3-eecfd07241e9 type=802-3-ethernet [802-3-ethernet] mac-address=52:54:00:8e:93:da slave-type=bridge master=Bridge
== The 'ifcfg' way
ifcfg-Bridge:
UUID=fc61f6e5-8900-4c6f-915c-eb55714eb874 TYPE=bridge DEVICE=wan3
ifcfg-Slave:
UUID=2e1906b1-92a4-4206-b2d3-eecfd07241e9 TYPE=Ethernet HWADDR=52:54:00:8e:93:da BRIDGE=wan3
