For each device there's a section like the following:
# Config information for eth0: Or whatever the eth may be
IPADDR[0]="" This is where you would enter the ip your trying ot assign it
NETMASK[0]="" Subnet mask goes here
USE_DHCP[0]="" Change this it no if your adding a static setting and to yes if you are removing one
DHCP_HOSTNAME[0]="" Do not touch this it is poison
Now scroll down to the bottom and you will see
# Default gateway IP address:
GATEWAY="" Set your default gateway here
