Ah, I see. So thats what happens to the gurus, and why wisdom is so
rarely found in the world nowadays...

Anyway, enjoy what You're doing! :)

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,
