Ok, I added the IP information to the ifcfg-br20 file and ifdown/ifup 
that interface. I am able to ping the 192.168.130.X range but nothing in 
the 192.168.131.X, 192.168.132.X, or 192.168.133.X ranges. Here is the 
contents of that file:
DEVICE=br20
TYPE=Bridge
BOOTPROTO=static
IPADDR=192.168.130.51
NETMASK=255.255.0.0
NETWORK=192.168.0.0
ONBOOT=yes


I know I am missing something simple. I know it should work as the 
windows 2008 r2 domu I have setup with 4 nics all on br20 is able to 
access all the ranges needed.
