When you use SnapLogic, the execution takes place on a Snaplex. If you are using a Snaplex located on your local machine, it should be able to connect. If you are using a Cloudplex, like the one in the SnapLogic free trial, you will not be able to connect to resources in you local environment unless they are reachable form the internet located Snaplex. If you have a Groundplex executing locally this may be feasible. Which are you using?
