Back to My Mac works fine when I disable the connection blocking in NIS 5 on my Mac with OS X 10.8.2. When I re-enable connection blocking NIS 5 blocks the connection and I cannot use Back to My Mac. I have configured the connection/service blocking to enable all connections for FileSharing, Back to My Mac, and Kerberos. It pops up a message about acces to Racoon which i Allow, but the Back to My Mac still doesn't connect from the remote computer. See error log note attached.
