subnet routing

I have an ISA server(gateway1) with an internal and external interface.  I
also have a Contivity 100 running in parallel to the ISA server.  The ISA
server is the default gateway for all workstations on the internal subnet.
 I would like to create a route on the ISA server such that ALL traffic to
a particular external subnet gets forwarded through the Contivity 100.

Here is my configuration (Names and ips have been changed to protect the
innocent)

ISA -
Gateway1(Internal Interface): 10.10.1.1
Gateway1(External Interface): 44.194.121.1

Contivity 100 - 
Gateway2(Internal Interface): 10.10.1.2
Gateway2(External Interface): 44.194.121.2

10.10.1.x workstation default gateway: Gateway1.

External Subnet for routing to Gateway2: 141.101.123.0/255.255.255.0

---

So I would like all requests from any workstation from the 10.10.1.x
subnet to the 141.101.123.0 network to get routed through Gateway2.

I tried adding a route on the ISA server using the following command with
no luck.

route -p add 141.101.123.0 MASK 255.255.255.0 10.10.1.2 METRIC 1

I know if I add this route on each workstation in the 10.10.1.x network
then it works fine.  I am trying to keep from having any special
configuration on every workstation.

Thanks for any help
Chris
