Sites? There was no mention of sites before. It was just two hubs. Exactly
how are these two LANs connected?
Routing is a two-way process. There must be a route (default or
specific) from A to B and also from B to A.
If the default gateway for 192.168.30.11 is to the RRAS router and the
default gateway for the RRAS router is the Cisco, routing in that direction
is fine. In the other direction, all you should need is the static route on
the Cisco to forward traffic for 192.168.30 to the RRAS router. Once it gets
to the RRAS router it will be delivered directly. If the static route on the
Cisco is correct you should be able to tracert from 10.1.1.x (including the
Cisco) to 192.168.30.11 (and yes, 10.1.1.2 should show up as a step in the
path).

Hi Bill,
Thanks for your answer.
I have Cisco 877 router on that site and that one has static route to
192.168.30.X setup.
I have RRAS active on a SBS server and no firewall software I know of.
One of the concerns is the following:
When I traceroute from 10.1.1.1 cisco router to 192.168.30.10, I am geting
no IP addresses showing in path. I presume 10.1.1.2 is suppose to show as
a
step in a path, but I can not see it. Is that because Cisco router is not
routing to the right gateway or because some block exists on SBS external
interface (10.1.1.2)?
Unfortunately, the site is far away and i do not have access to it. I also
have no remote access to 10.1.1.X workstations (no credentials to log on).
Regards,
Alex

The first thing you have to do is enable IP routing on the server, so
that it can forward the traffic. The next thing you need to do is add
extra
routing to get the traffic to the internal router.
The routing would look like this.
Internet
|
gateway
10.1.1.1
|
workstations
10.1.1.x dg 10.1.1.1
|
10.1.1.2 dg 10.1.1.1
server
192.168.30.10 dg blank
|
192.168.30.11 dg 192.168.30.10
To get the traffic from 10.1.1 to 192.168.30. you need to add a
static route to the gateway router.
192.168.30.0 255.255.255.0 10.1.1.2
If for some reason you can't add this to the gateway router you will
need to add it to every client in the 10.1.1 subnet which needs to access
the TS in 192.168.

This is (simplified) setup:
10.1.1.1 default gateway
|
HUB ----- 10.1.1.X - subnet with workgroup clients
|
10.1.1.2 as "external IP of SBS server
|
192.168.30.10 as internal IP of SBS server
|
HUB
|
192.168.30.11 Terminal server IP address
I know that setup is not very clever, but that is what I inherited and
can
not change.
The question is how to allow trafic originating from 10.1.1.X subnet to
reach 192.168.30.11 (terminal server)

Alex
