The OSX installer from OpenAFS.org uses a self-signed certificate to
sign both afsd and the kext.  In the past this has been sufficient to
permit the cache manager to receive traffic from endpoints that it
contacts provided that the firewall option

  Automatically allow signed software to receive
  incoming connections

is checked.

Note that the endpoint is the address and port.  You should not expect
to be able to query the cache manager with cmdebug or rxdebug with the
firewall enabled since the cache manager did not initiate contact with
those endpoints.

It is possible (and I haven't checked this) that Mavericks is no longer
permitting any packets to be received if the kext is legacy and/or
signed by a self-signed certificate.  I have confirmed that the OSX
installers provided by Your File System Inc. to its support customers do
successfully receive callbacks from file servers.  These installers are
Mavericks native (not legacy) and are signed using Apple issued
certificates.
