Routing Problem

[lance turner <latu@latu.net>]

I am having difficulty permanently adding a route to the routing table.

I used the following command to add a route:

route add -net default gw 192.168.1.3 dev eth0

This resulted in the following routing table:

Kernel IP routing table
Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface
192.168.1.0     *               255.255.255.0   U         0 0          0 eth0
127.0.0.0       *               255.0.0.0       U         0 0          0 lo
default         192.168.1.3     0.0.0.0         UG        0 0          0 eth0

But after restarting, the routing table changes to this:

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
192.168.1.0     *               255.255.255.0   U     0      0        0 eth0
127.0.0.0       *               255.0.0.0       U     0      0        0 lo
default         192.168.1.254   0.0.0.0         UG    0      0        0 eth0

Which does not work. The server can not get to the gateway and thus to the internet.

I also checked the/ proc/net/route file, and it matches what is displayed by "route" and "netstat -r".

/proc/net/route before restart

Iface	Destination	Gateway 	Flags	RefCnt	Use	Metric	Mask		MTU	Window	IRTT                                                       
eth0	0001A8C0	00000000	0001	0	0	0	00FFFFFF	0	0	0                                                                               
lo	0000007F	00000000	0001	0	0	0	000000FF	0	0	0                                                                                 
eth0	00000000	0301A8C0	0003	0	0	0	00000000	0	0	0                                                                               

/proc/net/route after restart:

Iface	Destination	Gateway 	Flags	RefCnt	Use	Metric	Mask		MTU	Window	IRTT                                                       
eth0	0001A8C0	00000000	0001	0	0	0	00FFFFFF	0	0	0                                                                               
lo	0000007F	00000000	0001	0	0	0	000000FF	0	0	0                                                                                 
eth0	00000000	FE01A8C0	0003	0	0	0	00000000	0	0	0     

The following is the from the /etc/sysconfig/network-scripts/ifcfg-eth0 file:

DEVICE=eth0
BOOTPROTO=static
BROADCAST=192.168.1.255
IPADDR=192.168.1.7
NETMASK=255.255.255.0
NETWORK=192.168.1.0
ONBOOT=yes

Obviously I'm doing something incorrect, but I'm not sure what. 

Any idea why the routing table is being modified at startup? What do I need to do to permanently set the routing table?

thanks,
