My router has a firewall. Otherwise, I don't know why I should be
concerned. I've used computers behind the router for over a decade and
there has never been a problem. My previous router didn't even have a
firewall, and still never a problem.

I am aware of the existence of /64 IPv6 address space, but I know zero
about it. Does this increase security concerns?
