Same on mine, manufacturers dumbing things down too much, because there is a
key difference between port forwarding and packet filtering.  In port
forwarding, the internal host can use a different port to what the public sees.
 With packet filtering, that's normally not possible, because the router is
doing nothing more than accepting or blocking traffic to a specific port on a
LAN host.  It is not rewriting packets.

So, when you're using IPv6, an extra constraint is that the host needs to be
listening on the same port that the public sees (My router only has a single
field for the port in IPv6).

True, I did have to pay for it. :)
