2 Internet routers 1 server

Hello,

I have:
1. Windows Server 2003 with IIS.
2. 2 routers DSL and CABLE from different ISP.
3. IP on cable router is static and has a DNS name (___.com). Any call to :80 is redirected to IIS on Windows Server 2003.
4. DSL’s router IP: 10.0.0.2
5. Cables’s router IP: 10.0.0.1

What I would like to do is:
1. The outbound Internet access must go through 10.10.0.2 (DSL).
2. Any request coming to ___.com (cable modem) and redirected to IIS must return through the cable modem.

Is it possible? Now it seems like any incoming request going out to DSL modem.

Thanks
Gennady
