The current KAME code does not support multiple tunnels between two hosts on a single interface. This restores that capability, which is required for setting up different overlay networks which use the same pairs of hosts. Such capability would be required for a 6-bone and a manually-configured IPSEC tunnel, supporting two separate overlays which both use tunnels between the same two hosts. This is a requirement of multiple overlapping overlays (which have many uses). The X-Bone is just a system that makes such overlays easier to deploy; we don't do anything that can't or wouldn't be done by a reasonable network administrator today. > - support issues (who handles questions about it? i don't want to) We would be happy to. We would also be glad to discuss further with you the issue of decapsulation of these packets, especially how to best determine the virtual interface number to put in the 'recvif' field.
