I have an app that connects to a service that's on localhost (I've tried http://127.0.0.1/myservice too)
When I "Run on Device" with a device connected the app fails to connect to the service. I am behind the corporate firewall. I've tried IPv4 address, localhost and 127.0.0.1 without luck.
Could this be related to the corporate network configuration? If so, what changes need to be made?

You are probably running into a so called NAT loopback issue. I have a similar problem when I want to access webservices that run on a PC at home when I am connected with my wifi at home.
[quote]Many DSL routers/modems prevent loopback connections as a security feature. This means that a machine on your local network (e.g. behind your DSL router/modem) cannot connect to a forward facing IP address (such as 199.149.252.44) of a machine that it also on your local network. Connecting to the local IP address (such as 192.168.2.40) of that same machine works fine.[/quote]
Is this on Android or iPhone/iPad? What I did was putting a proxy on one of my Windows machines. You can modify the hosts file on the machine so that a request to webservice.mydomain.com is forward to the ip of the PC running the web services.
