NT TCP/IP Routing problems with multiple network cards

I have two NT servers ('A' and 'B'), each with 3 network cards. I have configured TCP addresses as below and have RIP installed on both servers, with IP forwarding enabled. The subnet mask is set to 255.255.255.0 on all interfaces, including the clients.

My problem is that machines can only see (ping) machines on the same subnet. Trying to ping C1 from C2 or C4 from A doesn't work reporting no route to host.

'A' 192.168.2.x 'B'
192.168.1.x C1 ---------+---------------------------------+--------- C4 192.168.4.x
| |
| 192.168.5.x | 192.168.3.x
C2 C3

Server 'A' has NICs with addresses 192.168.1.1, 192.168.2.1 and 192.168.5.1
Server 'B' has NICs with addresses 192.168.3.1, 192.168.4.1 and 192.168.2.2
The clients are configured with an appropriate address for each subnet.

What should the correct subnet mask and default gateways be for each of the NT server interfaces and the clients? Does the fact that I am using private IP addresses cause problems with the routing?

Thanks for any help,

Ron

I think this may have worked, however I found that the problem was actually the default gateways on each of the NICS.

192.168.1.1 - Should have no gateway
192.168.5.1 - Should have no gateway
192.168.2.1 - Gateway 192.168.2.2
192.168.2.1 - Gateway 192.168.2.1
192.168.3.1 - Should have no gateway
192.168.4.1 - Should have no gateway

Having changed the settings to match these, the routing now works.

Thanks for the help.
