So....  You have 2 exact duplicates of my.ip.add.0?

Destination of 0.0.0.0 is the "default" route.  It should have an actual IP address
and a Genmask of 0.0.0.0 .

Here is mine....

Destination     Gateway         Genmask         Flags   MSS Window  irtt Iface
192.168.242.0   0.0.0.0         255.255.255.0   U         0 0          0 vmnet1
211.75.128.0    0.0.0.0         255.255.255.0   U         0 0          0 eth0
192.168.0.0     0.0.0.0         255.255.255.0   U         0 0          0 eth1
192.168.190.0   0.0.0.0         255.255.255.0   U         0 0          0 vmnet8
0.0.0.0         211.75.128.254  0.0.0.0         UG        0 0          0 eth0

I don't obfuscate my IP addresses....it doesn't make sense to do that....
