DECNet over IP?

Perhaps this question is not appropriate here... but I'm grasping at straws. Has anyone had any experience successfully getting native DECNet packets encapsulated in an IP packet and transmitted over an IP network? The solution I am trying to create will allow VAXes to continue to talk DECNet on their LANs and have the ability to communicate with DECNet areas on a WAN via IP. Essentially we are try to remove the DECNet protocol from our intranet while not disrupting location's DECNet configurations. If anyone has any info, please response off list. Thanks.
