Only, and only, if you configured your router that way.
In both cases, it's absolutely the same:
IPv4 -> allowed NAT ports -> NAT network -> Everything else is dropped/denied
IPv4 -> allowed ports -> directly routed IPv4 network -> Everything else is dropped/denied
IPv6 -> allowed ports -> directly routed IPv6 network -> Everything else is dropped/denied
See?
Of course if you are on someone's else network (typical for hosting when you aren't provided with your own v6 subnet, instead you have a bunch of addresses) then you should configure firewall on each your machine... which is what you need to do anyway?
