Re: Why this default route doesn't work ?

Tech-Archive recommends: Fix windows errors by optimizing your registry

If the mask is correct, the command should be:

route add 2.0.0.0 MASK 255.0.0.0 1.1.1.254

If the network ID is correct but the mask is wrong, the command should be:

route add 2.2.2.0 MASK 255.255.255.0 1.1.1.254

Also, if you only need to reach one machine as opposed to an entire network,
you can use a static route with the host IP and a full mask:

route add 2.2.2.2 MASK 255.255.255.255 1.1.1.254
