Will OpenVMS VAX 7.3 w/corresponding UCX install suffice for tunneling DECnet-over-IP (RFC1006) to other HECnet routers? Don't know the answer to that one, but Bob Armstrong and others do. I hope they'll chime in. Does UCX do DECnet tunneling over IP? AFAIK it has no such feature, but I haven't used it for years. If it does, then I'm afraid I know nothing about it. With Phase V + UCX you can definitely access OSI apps over IP (RFC1006). And I'm pretty sure I had DECnet sessions running over this, but couldn't swear to it. Seems logical though as I recall hazy memories of snippets of NCL configuration. Andrew
