I am integrating an application with database through Mule. I have exposed database queries as SOAP web services in Mule. In all there are 4 such services. These are in 4 different flows hence will be running on different ports. The problem is there is an internal firewall between application and Mule. I need to tell network administrator upfront the ports that I want to open up for inbound connections from application to Mule.
For any new service I need another HTTP port and ask for changes in firewall rules. One solution I could think of is having common entry flow (hence single HTTP port) which then delegates requests to other flows through VM or JMS transport. However I think it can be designed in better way to remove or minimize dependency on network configurations with multiple HTTP endpoints. Please advise.
