[tor-relays] Question about relay speed + quick question about IPV6

[Sheesh]

Thanks for everybody's input. I decided to move the relay keys to the
new server but I'm not entirely sure if I start another slow (500KB/s)
one or just seed some Linux distros or do something else helpful.

Also I do have a question about IPv6:
If I read right I just have to add
ORPort [IPv6]:Port
DirPort [IPv6]:Port
is this correct?
Can I specify the same ports I use for IPv4 (443 and 80)?

Also since I have a couple of IPv6 available but a non-exit relay is it
still necessary to set OutboundBindAddress?
