I'm trying to comunicate 2 subnets but there is now way to work.

I explain the situation:

1. Subnet 1 : 192.168.1.x/24
2. Subnet 2 : 192.168.0.x/24

I want to comunicate computer B (192.168.0.12) and computer C
(192.168.1.12). We have the computer A that have two NICS.

Computer A have the following IPs: 192.168.0.11 and 192.168.1.200

In the computer A I enable the IP Forwarding through the Register following
this instructions:
http://support.microsoft.com/Default.aspx?scid=kb;en-us;315236

I have in the route table of computer A the following rules:

Destination / Mask /
192.168.1.255 255.255.255.255 192.168.1.200 192.168.1.200
192.168.0.255 255.255.255.255 192.168.0.11 192.168.0.11

In the computer B I have the following rule

192.168.1.255 255.255.255.255 192.168.0.11 192.168.0.11

And in the computer C I have the following rule

192.168.0.255 255.255.255.255 192.168.1.12 192.168.1.12

But there is now way that ping of Computer B to Computer C responds.

What am I doing wrong?
 
The routing table doesn't look right. Re-post it by using route print.
