is it possible to set up a mixed node cluster for experimental use!!

i have one netware 6.5 test server and one linux oes sp1 server.
when i install the cluster services with the deploy manager i do the

- create new cluster
- select the tree, new cluster name ...
- choose netware server, node1 netware6.5, node2 linux

at this point i dind't have access to the linux server. "proxy-error"
any idea?
