Camel Netty component bind failure

Hello,

I am trying to use a tcp endpoint with camel netty. I need to establish a
two way route from a vert.x event bus to a remote server and viceversa.

Unluckily my vert.x uses Netty as well so when my netty producer is started
I get a low level Java exception: impossible to bind address:bind.

I suspect it is because my vertx local instance is using the same port as
netty. How can I change the local port a netty producer binds to?

Thanks

Edmondo
