Route add help on Windows Server 2003

Hello,



I wonder if all you gurus can give me a bit of help with routing in Windows
2003.



We have a server here in my office with an IP 192.168.2.20



The routers IP is 192.168.2.252



I want to talk to a server at the other end of the city with an IP
10.49.50.140



I thought it would be simple enough to open a command prompt and add a route
by typing:



route add 10.49.50.140 mask 255.0.0.0 192.168.0.252



When I do this I get an error saying The route addition failed: The
specified mask parameter is invalid. (Destination

& Mask) != Destination.



I though I would put a class A subnet mask as 255.0.0.0 as I was trying to
talk to a class A network? When I put the class C subnet in as
255.255.255.0 it will accept the route? Why does it work like this?



Any info or help would be gratefully received whilst I try to get my head
round this. Thank you.

Because you are putting the address in wrong. You dont want to route to a
specific host you want to route to a class A network. The command should
look more like this

route add 10.0.0.0 mask 255.0.0.0 192.168.0.252

In addition, just adding a route at your end doesn't mean that routing
will work. Routing is a two-way process. It will only work if the target
machine has enough routing info to know how to route the reply to your
machine.
