The problem is the following:
1) We have a machine with multiple interfaces (each one with its own IP), and we want to bind one specific IP to the ESB proxy services (for security reasons).
2) We are following WSO2 documentation in order to set up host name and ports: https://docs.wso2.com/display/ESB490/Setting+Up+Host+Names+and+Ports
3) We have changed the axis2.xml configuration file, editing the 2 parameters “bind-address” and “WSDLEPRPrefix” with the chosen IP:
<transportReceiver name="http" class="org.apache.synapse.transport.nhttp.HttpCoreNIOListener">
<parameter name="port" locked="false">8280</parameter>
<parameter name="bind-address" locked="false">10.10.16.15</parameter>
<parameter name="WSDLEPRPrefix" locked="false">http://10.10.16.15:8280</parameter>
</transportReceiver>
4) When we start the ESB the log outputs the following lines:
[01/20/2016 14: 13: 28.087] INFO - PassThroughHttpSSLListener Starting Pass-through HTTPS Listener ...
[01/20/2016 14: 13: 28.093] INFO - PassThroughListeningIOReactorManager Pass-through HTTPS Listener started on 0.0.0.0:8243
[01/20/2016 14: 13: 28.093] INFO - PassThroughHttpListener Starting Pass-through HTTP Listener ...
[01/20/2016 14: 13: 28.094] INFO - PassThroughListeningIOReactorManager Pass-through HTTP Listener started on 0.0.0.0:8280
We can see that on port 8280 all IPs (0.0.0.0) are bound, instead of 10.10.16.15. We also check the binding with netstat command.
NOTE: We also found that there was a bug on this configuration item (https://wso2.org/jira/browse/ESBJAVA-3117) that should have been solved in ESB version 4.9.0.
The os is Centos 7 with jdk oracle jdk1.7.0_79.
In the file axis2.xml there is this:
