Hi, have would appreciate some advice as i have been trying all day
and i am now stuck :( I was under the impression that any data coming
in on the dial in interface would have replies sent back out on the
same interface... it seems as if one of my servers doesnt know where
to send the reply.

I have a windows 2003 routing demand dial modem interface which calls
a small windows 2000 pro box which is running RAS.

I have set the link to dial when it sees packets goto the address
192.9.100.0.
The win2k3 server is also running on a lan segment with the IP address
192.9.200.0 (subnet mask 255.255.255.0).

When the connection is established to the win2k box i can ping from
the win2k3 server ok over the ppp link... however when i try to ping
from other machines on the win2k3 lan (for example machine
192.9.200.10) i see the ping get to the win2k box ok (with packet
sniffer), however no reply is sent back.

I am really stuck on how to procede, i am having trouble adding a
route on the win2k box to send any data out on the link that the
person has dialed in on, indeed im not sure i should need to do this?

I hope this makes sense, is what i am trying to do possible with win2k
professional? We are running this system remotely in some equipment so
we havent got the resources to run server.

Many thanks in advance,

Chris
 
sorry a point to add is that i have enabled routing on the win2k box by
changing the registry value to 1... i have included a dump from route
print below:

0x1 ........................... MS TCP Loopback interface

you have a routing issue. I don't see the default gateway in the routing table. Also what's the 127.0.0.0 255.0.0.0 for?

Thanks for the prompt reply Bob. With regard to your question, the
127.0.0.0 255.0.0.0 entry was put there by default, i have not added
any other routes (again was having problems with route add for the slip
connection and that was the only one i was trying to add routes for).

I will check out the site, it does seem like i have a routing issue. I
take it i can acheive what i want with windows professional RAS?

Cheers,
 
I have been playing about with RAS between two servers... works ok. Am
i correct in thinking that for the windows 2k box i would need to add a
route using netsh? When using 'route' the RAS interface isnt listed at
all, netsh seems like it is the tool to use (but complicated!). Any
advice much appreciated,

cheers,

Chris

I would stick with using servers. RRAS allows you to set up demand-dial
interfaces and link the routes to those interfaces. You don't have this
ability in Pro. You can't really set up a route until after the connection
is made (because the interface doesn't exist). With RRAS you can use the
demand-dial interface name to represent the connection and tie the routes to
the dd interface (using the new static route wizard in RRAS).
