Comment (by teor):

 Looking at the logs, tor appears to allow binding SOCKSPort to [::], but
 it warns you this is unsafe.
 `Mar 01 12:15:24.754 [warn] You specified a public address '[::]:9150' for
 SocksPort. Other people on the Internet might find your computer and use
 it as an open proxy. Please don't allow this unless you have a good
 reason.`

 Can you connect to the SOCKSPort on any of your IP addresses?

 Again looking at the logs, while tor allows you to bind ORPort to [::], it
 won't post a descriptor with [::] as the IPv6 address, because clients and
 other relays need to know one of your actual IPv6 addresses to connect to
 you.
 `Mar 01 12:17:06.000 [warn] Unable to use configured IPv6 address "[::]"
 in a descriptor. Skipping it. Try specifying a globally reachable address
 explicitly.`

 Try using an IPv6 address which can be reached on the Internet instead of
 `::` in your `ORPort [::]:4343` configuration line.
