Hi,
Add the following line in the /etc/rc.d/init.d/network script at the end
of "start" case:
/sbin/route add default gw <whatever is your default getway ip address>

OR
You can modify the /etc/sysconfig/network-scripts/ifcfg-eth* to add a
line as
GW=<whatever is your default getway ip address>
and modify the /etc/rc.d/init.d/network script if statement at the end of
"start" case. For example, here are few lines of what I've done in my script:

# Add non interface-specific static-routes.
if [ -f /etc/sysconfig/static-routes ]; then
grep "^any" /etc/sysconfig/static-routes | while read ignore type
dest netmask mask gw gateway; do
[ "${gateway}" != "${gateway##[0-9}" ] && \
/sbin/route add -$type $dest $netmask $mask $gw $gateway
done
fi

touch /var/lock/subsys/network
;;

best of luck!
