[rabbitmq-discuss] socket error while using rabbitmq and a NAT (Network address translation)

Sun Feb 27 13:06:58 GMT 2011

Hi ,
I am writing a new mail because my last issue was solved .
It is just that on a certain computer my application stopped working.
So it is a new issue and I will explain and paste the exception below.

Basically, I did three things :
1. I upgraded from 1.7.0 to 2.3.1 (installed a new erlang also)
2. I upgraded the client jars
3. changed the protocol to ack = true;

channel.basicConsume(queueName, true, queueingConsumer);

well, that certain computer is behind a firewall, and has a NAT (Network
Address Translation ).
It did work prior to the upgrade with the NAT (mySQL also handles it pretty
well).
with the same ports.
Maybe it is the bidirectional channel (since I added acking? I dont think
so...).

what I can see is that.
when the client tries to connect it writes in the logs

Connection closed abruptly

And now, behold, the exception :

PlatformException: com.rabbitmq.client.ShutdownSignalException:
