Comment:

 Please see my commit bug17027-reject-private-027-v4 on
 https://github.com/teor2345/tor.git

 It's based on tor 0.2.7.4-rc, and appears to merge cleanly into 0.2.8 /
 master.

 ExitPolicyRejectPrivate now blocks configured outbound bind addresses and
 port addresses (such as ORPort and DirPort).

 I'll create another bug for the backport to 0.2.6. (It's in bug17027
 -reject-private-026-v4.)
