Thanks Britt.

You mean like this right?

cat /etc/network/interfaces
=========================
# The loopback network interface
auto lo
iface lo inet loopback

# The primary network interface
auto eth0
iface eth0 inet dhcp

# The external network interface
auto br-ex
iface br-ex inet static
       address 192.168.122.54
       netmask 255.255.255.0
       gateway 192.168.122.1
       dns-nameservers 8.8.8.8 8.8.4.4
