RRAS - weird routing problem

Hi All
Trying to setup a basic routed and VLANed test lab

DSL modem/router 192.168.1.1
win xp sp1 192.168.1.22
RRAS VM LAN0 Nic 192.168.1.20
RRAS VM LAN1 Nic 172.10.10.2
Both RRAS nics have themselves as the default gateways
win2003 VM 172.10.10.5

Everything has a class C mask. Windows firewall is disabled on all boxes.
The enablerouter reg key has been set to 1 everywhere in the registry on the
RRAS box.

From RRAS can ping DSL
From XP can ping DSL

from XP can ping 2003 VM and from 2003 VM can ping XP.

XP and DSL are obviously on the same network. So the problem is I can ping
192.168.1.22 from the 172 net but not 192.168.1.1 ????

RRAS print route is:

Can anyone suggest anything?

You can't fix it by adding routes to the RRAS server. The main problem is
that the DSL router doesn't know where the 172 network is. You need a static
route on this router to redirect traffic for 172.10.10 to the RRAS router.
The setup should look like this. Note the default gateways on the RRAS
router.


Internet
|
router
192.168.1.1
static route 172.10.10.0 255.255.255.0 192.168.1.20
|
X P
192.168.1.22 dg 192.168.1.1
|
192.168.1.20 dg 192.168.1.1
RRAS
172.10.10.2 dg blank
|
server
172.10.10.5 dg 172.10.10.2

172.10 10.0 is not a reserved private IP address. Use 172.16.10.0 instead.

Thanks Bill of course ping has two sides. Sorry I'd been troubleshooting
RRAS all night just getting it working and got tunnel vision.

Hmm...complication I don't think with this router asus wl-600g you can add
static routes. Any other way to get the 172.x machines on the net?

You can get out to the Internet by configuring the RRAS router to do NAT.
But you won't be able to network between the 192.168. and 172.16 subnets
because the 192.168 is on the "public" side of the NAT.
