RRAS problem

[msnews.microsoft.com]

I would like to get RRAS working on a win 2k server with two network cards.

I have two subnets
192.168.0.xxx
192.168.1.xxx

The win2k server has IP
192.168.0.6
192.168.1.6

I can see all the machines on 0.xxx from 1.xxx
I can see all the machines on 1.xxx from 0.xxx

I need to be able to route to 2.xxx which goes through 192.168.1.1
I can see 192.168.1.6 from all of 2.xxx

On the gateway 192.168.0.1 I have a route to send 2.xxx to 192.168.0.6

I have a routing table on the win2k server

I would like to know why this is not working and if there is an example of
what to do.
thank you

Hi,
Can you post a simple network diagram to understand the setup better?
Also, specifically, its not clear where the machine 192.168.0.1 is located
in the network?

 

[msnews.microsoft.com]

There are three subnets

192.168.0.xxx
192.168.1.xxx
192.168.2.xxx

All three subnets have separate connections to the Internet through their
gateways
192.168.0.1
192.168.1.1
192.168.2.1

There is a VPN tunnel from 192.168.1.1 to 192.168.2.1
There is a server that is multi-homed (two network cards) at 192.168.1.6 and
192.168.0.6
This server has RRAS working and is successfully routing traffic between
0.xxx and 1.xxx

I would like traffic from 2.xxx to be able to get to 0.xxx by going through
1.6 and 0.6

Does this help? I'm not sure how to draw a diagram suitable in a text
message.
regards,
mark

Routing is a two-way process, so there are really two things you need to
check. The machines in 192.168.0.0 need to know how to reach 192.168.2.0 .
But more importantly the machines in 192.168.2.0 need to know how to reach
192.168.0.0 ! If it is across a VPN tunnel, then they must send the traffic
for 192.168.0.0 through the tunnel to 192.168.1.0 first.

So the clients in 192.168.0.0 must send traffic for both 192.168.1.0 and
192.168.2.0 to the RRAS router (to prevent it going to the Internet
gateway). Then the RRAS router must forward traffic for 192.168.2.0 across
the VPN link (to prevent it going to that subnet's Internet router by
default). This is the bit you have done.

At the other end, clients in 192.168.2.0 must send traffic for both
192.168.0.0 and 192.168.1.0 through the VPN tunnel. Then the tunnel endpoint
router must forward traffic for 192.168.0.0 to the RRAS router.

Hi Bill,

I thank you for your thoughts, though this does not give me the detail I
need to identify what the problem is.
As far as I can tell I have done what you outline. I need help from someone
with more specific detail.

regards,
Mark

There is no way to give you specific advice when we do not know what the
network looks like. That is why Sharoon asked for more detail about it. We
need to know how the subnets are interconnected and what default gateways
the routers and client machines have.
