This seems to work for me:
pass out route-to ($stf_if 2002:c058:6301::) from $stf_sn to !<my6nets>
pass out route-to $sixxs_if from $sixxs_sn to !<my6nets>
pass out route-to $he_if from $he_sn to !<my6nets>
My default route is to the remote address on $he_if.
Not sure what the key difference is though.
