Been a while since I used it but I used to use this script based on this
mkpeer fxp0: tee lower right
connect fxp0: fxp0:lower upper left
mkpeer fxp0:lower netflow right2left iface0
name fxp0:lower.right2left netflow
mkpeer netflow: ksocket export inet/dgram/udp
msg netflow:export connect inet/w.x.y.x:6667
hope that helps,
