With a firewall'd IPv6 network you just say - permit inbound :80. Done.
No need to port forward 80 on the external interface to A.B.C.D:80 on
some internal host. Or you can say permit inbound :80 just to
A.B.C.D.E.F. And if you want to access port 80 on two machines - no
problem. No need to have one be :80 and the other :81 as is required
with NAT (and makes for hackish URLs).

Except you're not supposed to run external services on the internal LAN at
all, because once a flaw has been discovered, your entire LAN with all its
desktops and everything is wide open. A LAN should be locked down,
totally, utterly. Saying "with IPv6 you can run services there" is simply not
an argument that wins any favours with me, and I hope any security conscious
admin agrees
