To start a network bridge, run the following:
ln -s /etc/init.d/net.lo /etc/init.d/net.br0
/etc/init.d/net.br0 start

If the network interface name is eth0, you will also have to remove the /etc/init.d/net.eth0 symlink and create /etc/init.d/net.br0:
/etc/init.d/net.eth0 stop
rm -f /etc/init.d/net.eth0
ln -s /etc/init.d/net.lo /etc/init.d/net.br0
/etc/init.d/net.br0 start
