If you are not short on bandwidth on the RT-link, why not using the non-RT tunnel to reach the second node via the first one? Then you only need two NICs on one of the two RT nodes, one NIC managed by RTnet, the other as usual by Linux. See the diagram on the RTnet documentation site. BTW, the LiRE preview I sent you does support this scenario quit conveniently, including a transparent router for node inside the RTnet domain. Hmm, I hope we can to make this tiny distribution publicly available soon as kind of quick-and-easy test for RTnet (and Xenomai). Jan
