I use enterprise equipment, so my examples
are likely not useful.

Firewalling for IPv6 using linux firewalld is no more
difficult than IPv4.  It is the same ports to block (or
allow), it is just potentially a different protocol.
The only difference is that you must do it with
IPv6, where as for IPv4 it is typically not needed
since your stateful NAT gateway does it for you.

I *think* someone once posted (in the wiki?)
the iptables example for running their Myth box
on the public internet.  But the ports are well
known (and are configurable).
