Hi

Is it possible to select routing table by ipfw setfib X ?

someting like:

ipfw add setfib 1 ip from a.b.c.d to any out xmit em0
setfib 1 route add default 10.10.10.1 


PS:
you may need to compile kernel with 
options ROUTETABLES=2

PPS:
why there is not sysctl way to specify number of routing tables ?
