Not necessarily. I've configured my IPv6 firewall to block all the things except for specific ip:port pairs. I didn't feel like leaving my network totally open.

IPv6 gives you the ability to make that choice for yourself rather than having it foisted upon you.

Indeed, in this case (and I'd imagine in most cases). IPv6 also gives your ISP the ability to make that choice for you; some ISP's, for example, block ports 25 and 80.

You setting up firewall rules at your gateway has no influence on whether an address is routable or not.
