Could be a network routing issue - packets from the client get through 
to the server but not vice versa. That's also consistent with your 
'telnet' observation.

I suggest you repeat your telnet experiment while logged into the same 
machine (i.e. while on rmq1 telnet to rabbitmq on that machine); if that 
works but remote connections don't then it's definitely a network issue.
