Microsoft SBS03, DSL Router, Satallite

I am learning to run MS SBS 03, have used 2 dsl routers for my network and have Direcway Satallite internet service. I just upgraded to DW6000 with an Ethernet connection, which is self hosted and cannot access the internet at all though the network. Does anyone have any knowledge that could help me to resolve this problem?
Thanks,
Joan
