Can I use one transport adapter on the nodes of the cluster?

Hi

I am new to sun cluster, in the cluster documentation they mentioned that each node should have 2 network cards one for public connections and one for private connection. what if I do not want the nodes to have public connections except for one node. In other words, I want to use one network card on each node except for the first node in the cluster, users can access the rest of the nodes through the fist node . Is that possible? If yes, what should be the name of the second transport adapter while installing the cluster software on the nodes.

Thank You for the help
