Re: Multihomed server 2000

Bill,

Thanks for responding.

Please let me clarify: I have a server with 2 NICs; one NIC is set to
192.168.0.5, and everything on this NIC is normal and active; I can ping it
from a computer attached to this interface.

I have a second NIC set to 192.168.200.1; if I attach a computer to this
interface, give the computer an address of 192.168.200.200 and from it ping
192.168.200.1 I get no reply.

Note that I'm not trying to ping the 192.168.200 net from 192.168.0 net; I'm
simply trying to ping the 192.168.200.1 server on that net, and it's not
responding. Setting a default gateway address of 192.168.200.1 in the
192.168.200.200 machine does not fix the problem.

If I run Network Monitor on the 192.168.200 NIC, I see the ping requests
arrive at the server, but the server doesn't respond. If I ping the .200
machine from the server, NM records nothing, although ping reports a
timeout. If I ping 192.168.200.1 from the server console, ping records a
normal response.

This seems like it should be clear and straightforward - what am I missing
here?

Thanks for your help.

Regards,
Dean

Default routing falls down when there are multiple routers involved.
The
main reason you cannot ping a machine in 192.168.200 froma workstation in
192.168.0 is that the default route is to 192.168.0.1, not to the RRAS
router. To get to 192.168.200 you need a specific route to get the traffic
to the RRAS router. You can add this route to each machine in 192.168.0 or
add it to the router at 192.168.0.1 . In either case this gets the traffic
for 192.168.200 to the RRAS router.

192.168.200.0 255.255.255.0 192.168.0.5

The second reason is that the machine in 192.168.200 does not have a
default gateway set. Set this to be the RRAS router interface in that
subnet
(192.168.200.1) so that there is a route back to the RRAS router for the
reply.

Bob,

I supplied ipconfig reports in my reply to Bill, but no, I did not
enable NAT on the second interface. I did enable LAN routing.

We need more information to help. Do you enable NAT since you have
two NICs? Posting the results of VPN server and client ipconfig /all
here may help.

Hello,

I've got a Win2K server with 2 NICs; one is set to 192.168.0.5
and is
connected to the LAN, the other is set to 192.168.200.1 (both
masks
255.255.255.0). The first works fine; I want to use the second
for VPNs,
but I can't ping it. It's enabled, I can see pings arriving, but
no
response. Any idea why? (No firewalls, BTW).

Thanks for any suggestions.
