Well, that does explain a bit. I'm not sure of the best way to troubleshoot ! this. It is extremely unlikely that it's broken on STABLE and fixed in ! 13.1-BETA or RC. ! ! Sorry I can't be more useful. If I had experience with FIBs on FreeBSD. ! It's not the same as RIBs and FIBs on Junipers. Thanks, no problem! I got all through it now, and in the end it was real fun and works now just as I imagined. I don't think fib are really flawed in 12.3 - but the ifconfig+routing interaction is better implemented in 13.1, it was worth the effort. And yesterday I got note that Andrey Elsukov put the "ipfw fwd" fix into HEAD, so this one will also go away now. Rock'n and Roll'n again! :) cheerio, PMc
