Unless you bridge the two interface, yes. Which interface do you start ND on?
For the OP, here is my ipv6 configuration.
tx0 is the internal net and is running with ULA as well as the /64 from HE.
sis0 is the external cable connection.
gif0 is the tunneled connection back to HE.
sft0 sends 6to4 reply traffic directly it is out bound only.
