You can test the connectivity definitively by getting a shell into each 
Erlang node and pinging the other. You need to do this while rabbit is 

E.g., on host rabbit1:

     $ rabbitmqctl stop_app

and on host rabbit2:

     $ rabbitmqctl stop_app

then on rabbit1 again:

     $ erl -remsh rabbit at rabbit1 -sname r1
     > net_adm:ping(rabbit at rabbit2).

which should give you the result 'pong';
then, on rabbit2

     $ erl -remsh rabbit at rabbit2 -sname r2
     > net_adm:ping(rabbit at rabbit1).

(and again expect 'pong').
