Thanks to JoeJulian on IRC for explaining to me, turns out there's no 
separation that would allow port based restriction.
So, in theory if a client can connect and mount a volume it can also 
issue "peer" commands, however - luckily - once a glusterfs deployment 
is setup an external node is not authorised to become a peer. For "peer 
probe" to work it needs to be initialised by an existing node.
