Win XP routing tables problem

[Joao]

Hello,

I'm currently having a problem related to my network.

I have multiple networks that must be connected. I need to be able to
have traffic between therm.

My Network: 192.168.100.0 width gateway 192.168.100.254
Other Networks: 192.168.210.0 and 192.168.230.0

I have a router (172.31.1.254) between my network and the others. I
currently have a machine , in my network with two NIC
NIC1 : 192.178.100.111 (no gateway defined)
NIC2: 172.31.1.1 (gateway defined 172.31.1.254)

I have defined some routing tables in this machine, equivalent to:

192.168.210.0 , 255.255.255.0 , 172.31.1.254 , Interface : NIC2
192.168.230.0 , 255.255.255.0 , 172.31.1.254 , Interface : NIC2

In this machin I can ping any address in class 192.168.210.x or
192.168.230.x.

The problem is, I can't ping any address in class 192.168.210.x or
192.168.230.x, from my other machines in my network. For example the
machine 192.178.100.114 can't access 192.168.210.x , eventhough I have
created the following rules in the this machine:

route add -p 192.168.210.0 mask 255.255.255.0 192.178.100.111
route add -p 192.168.230.0 mask 255.255.255.0 192.178.100.111

Can anyone help?

There's an inconsistency in the IP addressing that you describe. Your
network uses 192.168.100.0, but NIC1 has a 192.178 address, and the
routes on the other machines refer to that 192.178 address. I assume
that everything really uses 192.168 and that 178 is just a typo.

Enable TCP/IP forwarding on the 2-NIC machine to enable it to route
traffic between the NICs:

Hello again,

Yes the address 192.178 was a typo!

I started enabled TCP/IP forwarding, but it still doesn't work.

I still get "request timed out" on a ping request to any address in
192.168.210.x subnet, from any machine in the 192.168.100.x subnet

Regards
