You may need to set it in /etc/sysconfig/network-scripts/ifcfg-eth0.
It will look something like:
DEVICE=eth0
IPADDR=10.10.108.12
NETMASK=255.255.255.0
NETWORK=10.10.108.0
BROADCAST=10.10.108.255
GATEWAY=10.10.108.11
ONBOOT=yes
Just add the line for GATEWAY= if it's not there, or the address if it is.
Glad to help.
