Edit static route in the linux/windows

** add a specified route

METRIC 20 IF 4

Sometimes if we have dual interfaces in the windows host, and we get 2 DHCP-addresses/gateways from these two interfaces. So we want to disable one gateway, and only leave one gateway in the windows routing table. We can issue the following command...
** delete the default gateway of windows
C:\Documents and Settings\vincentlin>route DELETE 0.0.0.0 MASK 0.0.0.0 192.168.
