wso2 ESB: server configuration CRITICAL

Question

My Scenario: I have server_1 (192.168.10.1) with wso2-ESB and server_2 (192.168.10.2) with Glassfish-v3 + web services.

Problem: I am trying to create a proxy in ESB using the java Web Services, but the created proxy does not respond properly. The log says: Unable to sendViaPost for http or https does not change the result.

I think I should configure the axis2.xml but I am having trouble, and don't know what to do. What is the configuration for my scenario? Please help me!

EDIT: To be clear, I can directly consume the WebService in the Glassfish server, it works normal, both port and url are accessible. Only when I create a "Pass through Proxy" in the ESB, it does not work. I don't think is matter of Proxy configuration...I never had problems while deployed locally, problems started once I have uploaded the ESB to a remote server.

I really would need someone to point me what is the correct procedure when installing the ESB on a remote host: configuration of axis2.xml and carbon.xml, ports, transport receivers etc... P.S. I had a look at the official (wso2 esb and carbon) guides with no luck, but I am missing something...

Endpoint of Java Web Service: http://192.168.10.2:8080/HelloWorld/Hello?wsdl

ESB Proxy Enpoint: http://192.168.10.1:8280/services/HelloProxy

The following is my axis2.xml configuration, please check it:

<transportReceiver name="http" class="org.apache.synapse.transport.nhttp.HttpCoreNIOListener">
        <parameter name="port" locked="false">8280</parameter>

    </transportReceiver>

"Unable to sendViaPost", happens when the endpoint is not reachable. from where are you trying to access the proxy. what is the URL of the proxy. first try if you can access the host and the port of that URL.
