Yes.  Exactly like IPv4! (given that network security professionals have
existed for a long time)

Install a stateful firewall just like with IPv4!  Stateful firewalls
being things created by people "having a high level of knowledge
about ... internals".

Problem solved [for 99.44% of the population], just like IPv4!

And to add a nice sprinkling of obscurity - every time your computer
reboots [or interface resets] it generates a different ["random"] IPv6
address within your *HUGE* subnet.
