It sounds like a routing problem.  Bring both up and show us the output of
"netstat -nr"

The "default" router is the one where packets are sent to when you don't know where an IP address is.  You can only have one of them.  That is where all your internet requests go.

What exactly do you want to do?  You can route packets to certain sites through one particular interface but all the others will go to your default interface.
