I've used what I've found on the web and even copied a working config 
from a hypervisor at work running the same version of openSuSE (13.1) I 
use at home - nothing works at home.  The working config from the 
hypervisor (the only change is the IP address for home) is listed below, 
what am I doing wrong?  (Thanks for your help).

ifcfg-br0

    USERCONTROL='no'
    STARTMODE='auto'
    BOOTPROTO='static'
    BRIDGE='yes'
    BRIDGE_STP='off'
    BRIDGE_FORWARDDELAY='0'
    BRIDGE_PORTS='eth0'
    BRIDGE_PORTPRIORITIES='-'
    BRIDGE_PATHCOSTS='-'
    NETWORK=''
    NETMASK=''
    BROADCAST=''
    PREFIXLEN=''
    IPADDR='192.168.1.101/24'
    ETHTOOL_OPTIONS=''
    MTU=''
    NAME=''
    REMOTE_IPADDR=''

ifcfg-eth0

    BOOTPROTO='none'
    BROADCAST=''
    ETHTOOL_OPTIONS=''
    IPADDR=''
    MTU=''
    NAME='Intel Ethernet controller'
    NETMASK=''
    NETWORK=''
    REMOTE_IPADDR=''
    STARTMODE='auto'
    USERCONTROL='no'

I can't even ping the default gateway.  My configuration shows:

ip addr

ip route

default via 192.168.1.1 dev eth0  proto static
127.0.0.0/8 dev lo  scope link
192.168.1.0/24 dev eth0  proto kernel  scope link  src 192.168.1.6
192.168.1.0/24 dev br0  proto kernel  scope link  src 192.168.1.101

I previous (and now current) configuration was DHCP which is where 
probably the 192.168.1.6/24 comes from (and the DHCP scope stops at node 
100).
