Terminal to manage cluster, where the nodes are accessible from a remote PC?

I need to manage multiple cluster nodes from my PC. The catch is that the cluster nodes are accessible only from a remote PC. So first I have to ssh to the remote PC, and then ssh to a cluster node from the remote PC. If I had direct access to the nodes, I would use something like clusterssh to manage all the nodes simultaneously. Is there a tool similar to clusterssh that I can use in my situation?
