Yes, I have also router with pppd+ipf+nat+altq, but it is very small 
system (only ppp + 2 Ethernet interfaces). I'm interest in big system 
with dynamicaly routing and many network interfaces, but I have never 
seen it, therefore I find help in this group. I will try to contact 
Michael Richardson tomorrow.
