Thank you Sergio.
I'll try this again (I've tried it before it it didn't work, I suppose the 
problem with Amazon is that I need to publish the public IP - However the 
public IP is not assigned to an interface, it is internally routed to the 
private address by AWS):
httpclient.localaddress=1.2.3.4

Regarding this option:
remote_hosts=hostname:portname, hostname:portname,...

This is not the option I'm looking for. This option is for the client to 
initiate RMI communication with the agent. After that, the agent opens a 
connection back to the client using a specific port, and I'm looking for a way 
to pre-define that port.

Thanks,
Rodolfo
