I updated the BZ (and are now blocking 54321/tcp on one of my hosts).
and verified it is not reachable. As  general info: This system I am
using is my LAB / Test / eval setup for a final deployment for ovirt
(then 3.5) in production; so it will go away some time in the future (a
few weeks / months). If I am the only one experiencing this problem then
you might be better of allocating resources elsewhere ;)

As I said in my BZ comment this is not an option right now, but if
understand the matter correctly IPTABLES reject should ultimately do the
same?
