I use neither IPv6 nor pf, but if it's something dumb we're after then I
can ask some dumb questions:
- Is FTP running in passive mode or active mode?
- Is it running in the same mode in both IPv4 and IPv6?
- Do any of the rules that allow inbound traffic happen to allow in FTP-
  related traffic?  If you remove them does FTP over IPv4 still work?
- What ports does FTP over IPv6 use?

Good Luck!
