My current route for a box shows this:

 route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use 
Iface
24.123.23.168   0.0.0.0         255.255.255.248 U     0      0        0 eth2
74.223.8.176    0.0.0.0         255.255.255.240 U     0      0        0 eth1
192.168.1.0     0.0.0.0         255.255.255.0   U     0      0        0 eth0
169.254.0.0     0.0.0.0         255.255.0.0     U     0      0        0 eth2
0.0.0.0         24.123.23.169   0.0.0.0         UG    0      0        0 eth2

How do I setup the 74.223.8.176 route so on boot the gateway will 
automatically be
set to 74.223.8.177

Thanks,

Jerry
