LAN-to-LAN Routing

[Guest]

I am trying to configure a LAN-to-LAN router with my Windows 2000 server. I
have two NICs installed and they are configured:

NIC1
IP: 10.29.1.1
SUBMASK: 255.255.0.0

NIC2
IP: 10.22.4.10
SUBMASK 255.255.0.0

I have installed RRAS on the server and I can't get the two networks to
communicate to each other. When I ping the other network, it gets as far the
gateware NIC and stops. I also have DHCP configured on the 10.29.1.1 NIC. Any
help is appreciated.

What are the default gateway settings on the two subnets?

The traffic has to actually get to the router so that it can forward it
on to the other subnet. If this is the only router, set the clients in both
subnets to use it as the default gateway. eg

clients
10.29.x.y dg 10.29.1.1
|
10.29.1.1 dg blank
router
10.22.4.10 dg blank
|
clients
10.22.x.y dg 10.22.4.10

If there is another gateway which the clients use as a default, you will
need to add extra routing to get the local traffic to the internal (W2k)
router.

have you enabled ip routing? have you checked the inbound filtering and NAT?

I do have IP Routing enabled. Let me expand upon the network configuration I
have. Our current network is the 10.22.x.x subnet. This network's gateway to
the internet is 10.22.2.2. We are adding the 10.29.x.x subnet to our network.
We would like to have both subnets communicate with each other, which
includes being able to browse the both subnets. Both subnets should be able
to get to the internet through the 10.22.2.2 gateway. Also, DHCP is running
on the 10.29.x.x subnet through the NIC1 on the W2K router. How do I give out
the default gateway using the DHCP? I checked the configuration DHCP and did
not see the setting. Thanks.

That requires extra routing, because your Internet router doesn't know
anything about the new subnet. You will need to add extra routing to the
Internet router to tell it how to reach the new subnet.

Internet
|
router
10.22.2.2
|
10.22.x.y dg 10.22.2.2
|
10.22.4.10 dg 10.22.2.2
W2k
10.29.1.1 dg blank
|
10.29.x.y dg 10.29.1.1

The Internet router needs a route to forward 10.29.x.y traffic to the
Windows router. eg

10.29.0.0 255.255.0.0 10.22.4.10

The default gateway option in DHCP is 003 - Router.

OK, I'm almost there. Thank you so much for all this help. Everything works
except that I'm unable to ping a workstation on the new subnet (10.29.x.x)
from my existing subnet (10.22.x.x). I can only get a reply from the
10.29.1.1 gateway, but I can't ping the invidual workstations on the new
subnet (its range is 10.29.7.x). I did create the new route on the internet
router like you said so I know that isn't the isssue. Once again, thanks for
your help.

I figured out what was the problem and it was the workstation I was trying to
ping. Another workstation worked fine. Everything is configured correctly.
Thanks for all your help.
