How to create proxy service on a external application hosted outside of ESB Network and make sure that ports doesnot conflict ?

Issue

• Currently looking for proxy service on a external application hosted outside of ESB` Network.
• Followed url[1] to do the configuration.
• Using:

<route>
  <from uri="jetty:http://0.0.0.0:8183/myapp?matchOnUriPrefix=true"/>
  <to uri="jetty:http://hostname/1.0/?bridgeEndpoint=true&throwExceptionOnFailure=false"/>
</route>

• Currently all ESB services (cxf) are exposed on 8183. But once we give above configuration, then it conflicts for port...
• As per the design we are bound to use 8183 port for all proxy services on external load balancer(pre configured on port 8183) can be utilized for balancing these proxy services.
