If the source block is not routed via both connections it won't work without
NAT.  I had this same problem trying to use my ISP's native v6 over PPPoE
and maintain a tunnel as backup since it was still pretty flaky as they were
testing it at the time ... no way a residential ISP is going to route 3rd
party blocks for all their customers, and no chance the tunnel provider was
going to route the block my ISP assigned me either ... with no NAT66 in
Tomato/ddWRT/etc it was 100% impossible to have multiple connections ...
