Well first my line has [2]. I changed that to [1] and tried all sorts
of variants to the above, including putting a - infront of InTransports
(like other options), and replacing the = with a space. No listening on
IPv6.
I have foudn the RealVNC support mailing list and sent a question there,
hopefully to get answers. But if anyone has anything to suggest here,
please do.
